Implemetation for From<std::io::ErrorKind> for this crate

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).

Interrupted

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.

Other

Any I/O error not part of this list.

Errors that are Other now may move to a different or a new ErrorKind variant in the future. It is not recommended to match an error against Other and to expect any additional characteristics, e.g., a specific Error::raw_os_error return value.

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.

OutOfMemory

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

UnsupportedErrorKind

ErrorKind encountered is not yet supported

Trait Implementations

impl BorshDeserialize for IoErrorKind

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

impl BorshSerialize for IoErrorKind

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8, Global>, Error>

Serialize this instance into a vector of bytes.

impl Clone for IoErrorKind

fn clone(&self) -> IoErrorKind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IoErrorKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for IoErrorKind

fn cmp(&self, other: &IoErrorKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self where
    Self: PartialOrd<Self>, 

Restrict a value to a certain interval.

impl PartialEq<IoErrorKind> for IoErrorKind

fn eq(&self, other: &IoErrorKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<IoErrorKind> for IoErrorKind

fn partial_cmp(&self, other: &IoErrorKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
