}

All possible kinds of errors that can be returned

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

TimedOut

The I/O operation’s timeout expired, causing it to be cancelled

WriteZero

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

Interrupted

This operation was interrupted

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

Unsupported

This operation is unsupported on this platform

OutOfMemory

An operation could not be completed, because it failed to allocate enough memory

Loop

When a loop is encountered when walking a directory

TaskCancelled

When a task is cancelled

TaskPanicked

When a task panics

Unknown

Catchall for an error that has no specific type
