Trait Implementations

impl Host for WasiHttpCtxView<'_>

fn convert_error_code( &mut self, error: TrappableError<ErrorCode>, ) -> Result<ErrorCode>

fn convert_header_error( &mut self, error: TrappableError<HeaderError>, ) -> Result<HeaderError>

fn convert_request_options_error( &mut self, error: TrappableError<RequestOptionsError>, ) -> Result<RequestOptionsError>

impl HostFields for WasiHttpCtxView<'_>

fn new(&mut self) -> Result<Resource<Fields>>

Construct an empty HTTP Fields.

fn from_list( &mut self, entries: Vec<(FieldName, FieldValue)>, ) -> Result<Resource<Fields>, TrappableError<HeaderError>>

Construct an HTTP Fields.

fn get( &mut self, fields: Resource<Fields>, name: FieldName, ) -> Result<Vec<FieldValue>>

Get all of the values corresponding to a name. If the name is not present in this fields, an empty list is returned. However, if the name is present but empty, this is represented by a list with one or more empty field-values present.

fn has(&mut self, fields: Resource<Fields>, name: FieldName) -> Result<bool>

Returns true when the name is present in this fields. If the name is syntactically invalid, false is returned.

fn set( &mut self, fields: Resource<Fields>, name: FieldName, value: Vec<FieldValue>, ) -> Result<(), TrappableError<HeaderError>>

Set all of the values for a name. Clears any existing values for that name, if they have been set.

fn delete( &mut self, fields: Resource<Fields>, name: FieldName, ) -> Result<(), TrappableError<HeaderError>>

Delete all values for a name. Does nothing if no values for the name exist.

fn get_and_delete( &mut self, fields: Resource<Fields>, name: FieldName, ) -> Result<Vec<FieldValue>, TrappableError<HeaderError>>

Delete all values for a name. Does nothing if no values for the name exist.

fn append( &mut self, fields: Resource<Fields>, name: FieldName, value: FieldValue, ) -> Result<(), TrappableError<HeaderError>>

Append a value for a name. Does not change or delete any existing values for that name.

fn copy_all( &mut self, fields: Resource<Fields>, ) -> Result<Vec<(FieldName, FieldValue)>>

Retrieve the full set of names and values in the Fields. Like the constructor, the list represents each name-value pair.

fn clone(&mut self, fields: Resource<Fields>) -> Result<Resource<Fields>>

Make a deep copy of the Fields. Equivalent in behavior to calling the fields constructor on the return value of copy-all. The resulting fields is mutable.

fn drop(&mut self, fields: Resource<Fields>) -> Result<()>

impl HostRequest for WasiHttpCtxView<'_>

fn get_method(&mut self, req: Resource<Request>) -> Result<Method>

Get the Method for the Request.

fn set_method( &mut self, req: Resource<Request>, method: Method, ) -> Result<Result<(), ()>>

Set the Method for the Request. Fails if the string present in a method.other argument is not a syntactically valid method.

fn get_path_with_query( &mut self, req: Resource<Request>, ) -> Result<Option<String>>

Get the combination of the HTTP Path and Query for the Request. When none, this represents an empty Path and empty Query.

fn set_path_with_query( &mut self, req: Resource<Request>, path_with_query: Option<String>, ) -> Result<Result<(), ()>>

Set the combination of the HTTP Path and Query for the Request. When none, this represents an empty Path and empty Query. Fails is the string given is not a syntactically valid path and query uri component.

fn get_scheme(&mut self, req: Resource<Request>) -> Result<Option<Scheme>>

Get the HTTP Related Scheme for the Request. When none, the implementation may choose an appropriate default scheme.

fn set_scheme( &mut self, req: Resource<Request>, scheme: Option<Scheme>, ) -> Result<Result<(), ()>>

Set the HTTP Related Scheme for the Request. When none, the implementation may choose an appropriate default scheme. Fails if the string given is not a syntactically valid uri scheme.

fn get_authority(&mut self, req: Resource<Request>) -> Result<Option<String>>

Get the authority of the Request’s target URI. A value of none may be used with Related Schemes which do not require an authority. The HTTP and HTTPS schemes always require an authority.

fn set_authority( &mut self, req: Resource<Request>, authority: Option<String>, ) -> Result<Result<(), ()>>

Set the authority of the Request’s target URI. A value of none may be used with Related Schemes which do not require an authority. The HTTP and HTTPS schemes always require an authority. Fails if the string given is not a syntactically valid URI authority.

fn get_options( &mut self, req: Resource<Request>, ) -> Result<Option<Resource<RequestOptions>>>

Get the request-options to be associated with this request

fn get_headers(&mut self, req: Resource<Request>) -> Result<Resource<Headers>>

Get the headers associated with the Request.

impl HostRequestOptions for WasiHttpCtxView<'_>

fn new(&mut self) -> Result<Resource<RequestOptions>>

Construct a default request-options value.

fn get_connect_timeout( &mut self, opts: Resource<RequestOptions>, ) -> Result<Option<Duration>>

The timeout for the initial connect to the HTTP Server.

fn set_connect_timeout( &mut self, opts: Resource<RequestOptions>, duration: Option<Duration>, ) -> Result<(), TrappableError<RequestOptionsError>>

Set the timeout for the initial connect to the HTTP Server. An error return value indicates that this timeout is not supported or that this handle is immutable.

fn get_first_byte_timeout( &mut self, opts: Resource<RequestOptions>, ) -> Result<Option<Duration>>

The timeout for receiving the first byte of the Response body.

fn set_first_byte_timeout( &mut self, opts: Resource<RequestOptions>, duration: Option<Duration>, ) -> Result<(), TrappableError<RequestOptionsError>>

Set the timeout for receiving the first byte of the Response body. An error return value indicates that this timeout is not supported or that this handle is immutable.

fn get_between_bytes_timeout( &mut self, opts: Resource<RequestOptions>, ) -> Result<Option<Duration>>

The timeout for receiving subsequent chunks of bytes in the Response body stream.

fn set_between_bytes_timeout( &mut self, opts: Resource<RequestOptions>, duration: Option<Duration>, ) -> Result<(), TrappableError<RequestOptionsError>>

Set the timeout for receiving subsequent chunks of bytes in the Response body stream. An error return value indicates that this timeout is not supported or that this handle is immutable.

fn clone( &mut self, opts: Resource<RequestOptions>, ) -> Result<Resource<RequestOptions>>

Make a deep copy of the request-options. The resulting request-options is mutable.

fn drop(&mut self, opts: Resource<RequestOptions>) -> Result<()>

impl HostResponse for WasiHttpCtxView<'_>

fn get_status_code(&mut self, res: Resource<Response>) -> Result<StatusCode>

Get the HTTP Status Code for the Response.

fn set_status_code( &mut self, res: Resource<Response>, status_code: StatusCode, ) -> Result<Result<(), ()>>

Set the HTTP Status Code for the Response. Fails if the status-code given is not a valid http status code.

fn get_headers(&mut self, res: Resource<Response>) -> Result<Resource<Headers>>

Get the headers associated with the Response.
