Struct zc_io::Error

pub struct Error { /* private fields */ }

The error type for zero-copy I/O operations of the Read and Write traits.

When std is enabled this becomes a zero-cost abstraction over io::Error. In no_std environments, error messages are preserved while io::ErrorKind information is stripped.

If you are working in an environment that may be no_std, and you need to create an Error yourself, use the error! macro.

Implementations

impl Error

pub fn new<E>(kind: ErrorKind, error: E) -> Errorwhere
E: Into<Box<dyn Error + Send + Sync>>,

Available on crate feature std only.

Creates a new I/O error from a known kind of error as well as an arbitrary error payload.

For more information, refer to io::Error::new.

pub fn other<E>(error: E) -> Errorwhere
E: Into<Box<dyn Error + Send + Sync>>,

Available on crate feature std only.

Creates a new I/O error from an arbitrary error payload.

For more information, refer to io::Error::other.

pub fn last_os_error() -> Error

Available on crate feature std only.

Returns an error representing the last OS error which occurred.

For more information, refer to io::Error::last_os_error.

pub fn from_raw_os_error(code: i32) -> Error

Available on crate feature std only.

Creates a new instance of an Error from a particular OS error code.

For more information, refer to io::Error::from_raw_os_error.

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

Available on crate feature std only.

Returns the OS error that this error represents (if any).

For more information, refer to io::Error::raw_os_error.

pub fn get_ref(&self) -> Option<&(dyn Error + Send + Sync + 'static)>

Available on crate feature std only.

Returns a reference to the inner error wrapped by this error (if any).

For more information, refer to io::Error::get_ref.

pub fn get_mut(&mut self) -> Option<&mut (dyn Error + Send + Sync + 'static)>

Available on crate feature std only.

Returns a mutable reference to the inner error wrapped by this error (if any).

For more information, refer to io::Error::get_mut.

pub fn into_inner(self) -> Option<Box<dyn Error + Send + Sync>>

Available on crate feature std only.

Consumes the Error, returning its inner error (if any).

For more information, refer to io::Error::into_inner.

pub fn kind(&self) -> ErrorKind

Available on crate feature std only.

Returns the corresponding ErrorKind for this error.

For more information, refer to io::Error::kind.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

impl Error for Error

Available on crate feature std only.

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