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 futures 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 futures 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.
