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.

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.
