Expand description

I/O error categories.

This list may grow, and it is not recommended to match against it.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown = 0

Catch-all I/O error.

NotOpen = 1

An I/O operation was attempted when the transport channel was not open.

AlreadyOpen = 2

The transport channel cannot be opened because it was opened previously.

TimedOut = 3

An I/O operation timed out.

EndOfFile = 4

A read could not complete because no bytes were available.

NegativeSize = 5

An invalid (buffer/message) size was requested or received.

SizeLimit = 6

Too large a buffer or message size was requested or received.

Trait Implementations§

impl Clone for TransportErrorKind

fn clone(&self) -> TransportErrorKind

Returns a copy of the value. Read more

1.0.0 · Source§

impl PartialEq for TransportErrorKind

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

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

1.0.0 · Source§

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

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