Cases

Case	Payload	Description
access-denied	—	Access denied.
not-supported	—	The operation is not supported.
invalid-argument	—	One of the arguments is invalid.
out-of-memory	—	Not enough memory to complete the operation.
timeout	—	The operation timed out before it could finish completely.
invalid-state	—	The operation is not valid in the socket's current state.
address-not-bindable	—	The local address is not available.
address-in-use	—	A bind operation failed because the provided address is already in use or because there are no ephemeral ports available.
remote-unreachable	—	The remote address is not reachable.
connection-refused	—	The connection was forcefully rejected.
connection-broken	—	A write failed because the connection was broken.
connection-reset	—	The connection was reset.
connection-aborted	—	The connection was aborted.
datagram-too-large	—	The size of a datagram sent to a UDP socket exceeded the maximum supported size.
other	option<string>	A catch-all for errors not captured by the existing variants. Implementations can use this to extend the error type without breaking existing code.
