1.0.0[−][src]Enum futures::io::ErrorKind
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 (Non-exhaustive)
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.

impl From<ErrorKind> for Error
1.14.0[src]
impl From<ErrorKind> for Error
Intended for use for errors not exposed to the user, where allocating onto the heap (for normal construction via Error::new) is too costly.
fn from(kind: ErrorKind) -> Error
[src]
fn from(kind: ErrorKind) -> Error
Converts an [ErrorKind
] into an [Error
].
This conversion allocates a new error with a simple representation of error kind.
Examples
use std::io::{Error, ErrorKind}; let not_found = ErrorKind::NotFound; let error = Error::from(not_found); assert_eq!("entity not found", format!("{}", error));
