Struct Classification 

pub struct Classification<'a> { /* private fields */ }

A semantic class together with the concrete error which established it.

Implementations

impl<'a> Classification<'a>

pub fn class(&self) -> Class

Return the semantic class.

pub fn error(&self) -> &'a (dyn Error + 'static)

Return the concrete error which established the classification.

A source-bearing crate::ClassificationMarker identifies its wrapped error. A class-only marker supplied through a native source() identifies the error that owns it. A standalone marker without an identifiable subject retains the marker itself as a fallback.

pub fn io_kind(&self) -> Option<ErrorKind>

Return the original I/O error kind, if the underlying error is an std::io::Error.

Trait Implementations

impl<'a> Clone for Classification<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Classification<'a>

impl<'a> Debug for Classification<'a>

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

Formats the value using the given formatter.
