[−][src]Struct err_context::Context
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.
Methods
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.
impl<M> Context<M, Compat<Error>>[src]
pub fn from_failure(msg: M, failure: Error) -> Self[src]
Constructor of context from a failure's Error.
This is a compatibility constructor, for wrapping the error of failure. It is enabled by
the failure feature.
Warning
The compatibility layer has no way to access the original causes of the failure. Therefore, the inner layers of the provided failure will be lost and the failure will be considered the innermost level.
impl<M, F: Fail> Context<M, Compat<F>>[src]
pub fn from_fail(msg: M, failure: F) -> Self[src]
Constructor of context from a failure's Fail.
This is a compatibility constructor, for wrapping failure. It is enabled by the failure
feature.
Warning
The compatibility layer has no way to access the original causes of the failure. Therefore, the inner layers of the provided failure will be lost and the failure will be considered the innermost level.
