Struct Error 

pub struct Error { /* private fields */ }

An error returned by a VFS operation.

In addition to a portable ErrorKind, this retains the original message and, when available, the originating system’s native error number.

Implementations

impl Error

pub fn new(kind: ErrorKind, message: impl ToString) -> Self

Creates an error without a native error number.

pub fn other(error: impl ToString) -> Self

Creates an unclassified error from a displayable value.

pub fn from_system_code( kind: ErrorKind, message: impl Into<String>, operating_system: OperatingSystem, raw: i32, ) -> Self

Creates an error with a native error number and its source platform.

pub fn from_raw_os_error(raw: i32) -> Self

Converts a native error number from the current host.

pub fn last_os_error() -> Self

Captures the calling thread’s last operating-system error.

pub fn from_raw_os_error_with_message( raw: i32, message: impl Into<String>, ) -> Self

Converts a native error number from the current host while preserving a caller-supplied message.

pub fn from_raw_os_error_with_kind(raw: i32, kind: ErrorKind) -> Self

Converts a native error number from the current host while preserving a caller-supplied kind.

pub const fn kind(&self) -> ErrorKind

Returns this error’s portable classification.

pub fn message(&self) -> &str

Returns the human-readable error message.

pub const fn system_code(&self) -> Option<SystemCode>

Returns the tagged native error number, if one was supplied.

pub const fn raw_os_error(&self) -> Option<i32>

Returns the untagged native error number, if one was supplied.

pub fn into_io_error(self) -> Error

Converts this error into io::Error, preserving its portable kind.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
