Struct ErrorAndSerializer

Source
pub struct ErrorAndSerializer<E, S> {
    pub error: E,
    pub serializer: S,
}
Expand description

An error and a serializer.

This error type encodes the common pattern of returning an error and the original serializer that caused the error. For brevity, users are encouraged to alias this to local types.

It provides a From implementation from (E, S) for convenience and impedance matching with the [packet] crate.

Fields§

§error: E

The error observed.

§serializer: S

The serializer accompanying the error.

Implementations§

Source§

impl<E, S> ErrorAndSerializer<E, S>

Source

pub fn map_serializer<N, F: FnOnce(S) -> N>( self, f: F, ) -> ErrorAndSerializer<E, N>

Changes the serializer type.

Source

pub fn map_err<N, F: FnOnce(E) -> N>(self, f: F) -> ErrorAndSerializer<N, S>

Changes the error type.

Source

pub fn err_into<N: From<E>>(self) -> ErrorAndSerializer<N, S>

Changes the error type using Into::into.

Source

pub fn into_err(self) -> E

Consumes this pair and returns only the error, dropping the serializer.

Source§

impl<E, I, O> ErrorAndSerializer<E, Nested<I, O>>

Source

pub fn into_inner(self) -> ErrorAndSerializer<E, I>

A convenience function for dealing with [Nested] serializers.

Equivalent to using ErrorAndSerializer::map_serializer.
