Expand description
Error codes.
In theory, every API can return any error code. In practice, API’s typically only return the errors documented per API combined with a couple of errors that are always possible:
unknown
access-denied
not-supported
out-of-memory
concurrency-conflict
See each individual API for what the POSIX equivalents are. They sometimes differ per API.
Variants§
Unknown = 0
Unknown error
AccessDenied = 1
Access denied.
POSIX equivalent: EACCES, EPERM
NotSupported = 2
The operation is not supported.
POSIX equivalent: EOPNOTSUPP
InvalidArgument = 3
One of the arguments is invalid.
POSIX equivalent: EINVAL
OutOfMemory = 4
Not enough memory to complete the operation.
POSIX equivalent: ENOMEM, ENOBUFS, EAI_MEMORY
Timeout = 5
The operation timed out before it could finish completely.
ConcurrencyConflict = 6
This operation is incompatible with another asynchronous operation that is already in progress.
POSIX equivalent: EALREADY
NotInProgress = 7
Trying to finish an asynchronous operation that:
- has not been started yet, or:
- was already finished by a previous
finish-*
call.
Note: this is scheduled to be removed when future
s are natively supported.
WouldBlock = 8
The operation has been aborted because it could not be completed immediately.
Note: this is scheduled to be removed when future
s are natively supported.
InvalidState = 9
The operation is not valid in the socket’s current state.
NewSocketLimit = 10
A new socket resource could not be created because of a system limit.
AddressNotBindable = 11
A bind operation failed because the provided address is not an address that the network
can bind to.
AddressInUse = 12
A bind operation failed because the provided address is already in use or because there are no ephemeral ports available.
RemoteUnreachable = 13
The remote address is not reachable
ConnectionRefused = 14
The TCP connection was forcefully rejected
ConnectionReset = 15
The TCP connection was reset.
ConnectionAborted = 16
A TCP connection was aborted.
DatagramTooLarge = 17
The size of a datagram sent to a UDP socket exceeded the maximum supported size.
NameUnresolvable = 18
Name does not exist or has no suitable associated IP addresses.
TemporaryResolverFailure = 19
A temporary failure in name resolution occurred.
PermanentResolverFailure = 20
A permanent failure in name resolution occurred.
