}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
NotFoundAn entity was not found, often a file.
PermissionDeniedThe operation lacked the necessary privileges to complete.
ConnectionRefusedThe connection was refused by the remote server.
ConnectionResetThe connection was reset by the remote server.
ConnectionAbortedThe connection was aborted (terminated) by the remote server.
NotConnectedThe network operation failed because it was not connected yet.
AddrInUseA socket address could not be bound because the address is already in use elsewhere.
AddrNotAvailableA nonexistent interface was requested or the requested address was not local.
BrokenPipeThe operation failed because a pipe was closed.
AlreadyExistsAn entity already exists, often a file.
WouldBlockThe operation needs to block to complete, but the blocking operation was requested to not occur.
InvalidInputA parameter was incorrect.
InvalidDataData 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.
TimedOutThe I/O operation's timeout expired, causing it to be canceled.
WriteZeroAn 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.
InterruptedThis operation was interrupted.
Interrupted operations can typically be retried.
OtherAny I/O error not part of this list.
UnexpectedEofAn 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.

impl From<ErrorKind> for Error1.14.0[src]
Intended for use for errors not exposed to the user, where allocating onto the heap (for normal construction via Error::new) is too costly.
