Struct StdError

Source 
pub struct StdError<K: ErrorKind = String> { /* private fields */ }
Expand description

The StdError type is a generic error type that is generic over the error kind; this enables us to distinguish between distinctly different error types.

Implementations§

Source§

impl<K> StdError<K>
where K: ErrorKind,

Source

pub fn kind(&self) -> &K

returns a reference to the kind of error

Source

pub fn kind_mut(&mut self) -> &mut K

returns a mutable reference to the kind of error

Source

pub fn message(&self) -> &str

returns a reference to the message

Source

pub fn set_kind(&mut self, value: K) -> &mut Self

update the kind before returning a mutable reference to the current instance.

Source

pub fn set_message<V: ToString>(&mut self, value: V) -> &mut Self

update the message before returning a mutable reference to the current instance.

Source

pub fn with_kind(self, kind: K) -> Self

consumes the current instance to create another with the given kind

Source

pub fn with_message(self, message: String) -> Self

consumes the current instance to create another with the given message.
