[−][src]Struct err_context::Context

pub struct Context<M, E> { /* fields omitted */ }

Additional level of context, wrapping some error inside itself.

This is produced by the context and implements the additional (outer) layer in the chain. Any number of contexts can be chained together.

Implementations

`impl<M, E> Context<M, E>`[src]

`pub fn new(msg: M, error: E) -> Self`[src]

A direct constructor for the context.

More usually created by the context, but allowing for construction directly without importing the trait.

`pub fn into_inner(self) -> E`[src]

Extracts the inner error, peeling off the outer layer.
