}

A list specifying general categories of I/O error.

This list is intended to grow over time and it is not recommended to exhaustively match against it.

It is used with the io::Error type.

Variants

NotFound

An entity was not found, often a file.

PermissionDenied

The operation lacked the necessary privileges to complete.

ConnectionRefused

The connection was refused by the remote server.

ConnectionReset

The connection was reset by the remote server.

ConnectionAborted

The connection was aborted (terminated) by the remote server.

NotConnected

The network operation failed because it was not connected yet.

AddrInUse

A socket address could not be bound because the address is already in use elsewhere.

AddrNotAvailable

A nonexistent interface was requested or the requested address was not local.

BrokenPipe

The operation failed because a pipe was closed.

AlreadyExists

An entity already exists, often a file.

WouldBlock

The operation needs to block to complete, but the blocking operation was requested to not occur.

InvalidInput

A parameter was incorrect.

InvalidData

Data not valid for the operation were encountered.

Unlike InvalidInput, this typically means that the operation parameters were valid, however the error was caused by malformed input data.

For example, a function that reads a file into a string will error with InvalidData if the file's contents are not valid UTF-8.

TimedOut

The I/O operation's timeout expired, causing it to be canceled.

WriteZero

An error returned when an operation could not be completed because a call to write returned Ok(0).

This typically means that an operation could only succeed if it wrote a particular number of bytes but only a smaller number of bytes could be written.

Interrupted

This operation was interrupted.

Interrupted operations can typically be retried.

Other

Any I/O error not part of this list.

UnexpectedEof

An error returned when an operation could not be completed because an "end of file" was reached prematurely.

This typically means that an operation could only succeed if it read a particular number of bytes but only a smaller number of bytes could be read.
