Trait Implementations

impl Clone for Errno

fn clone(&self) -> Errno

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Errno

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Errno

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Errno

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Errno> for Errno

fn from(e: Errno) -> Errno

Converts to this type from the input type.

impl From<Errno> for Error

fn from(abi: Errno) -> Error

Converts to this type from the input type.

impl From<Errno> for u16

fn from(v: Errno) -> u16

Converts to this type from the input type.

impl GuestErrorType for Errno

fn success() -> Self

impl GuestType for Errno

fn guest_size() -> u32

Returns the size, in bytes, of this type in the guest memory.

fn guest_align() -> usize

Returns the required alignment of this type, in bytes, for both guest and host memory.

fn read( mem: &GuestMemory<'_>, location: GuestPtr<Self>, ) -> Result<Self, GuestError>

Reads this value from the provided ptr.

fn write( mem: &mut GuestMemory<'_>, location: GuestPtr<Self>, val: Self, ) -> Result<(), GuestError>

Writes a value to ptr after verifying that ptr is indeed valid to store val.

impl PartialEq for Errno

fn eq(&self, other: &Errno) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<i32> for Errno

type Error = GuestError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Errno, GuestError>

Performs the conversion.

impl TryFrom<u16> for Errno

type Error = GuestError

The type returned in the event of a conversion error.

fn try_from(value: u16) -> Result<Errno, GuestError>

Performs the conversion.

impl Copy for Errno

impl StructuralPartialEq for Errno
