[][src]Struct failure::Context

pub struct Context<D: Display + Send + Sync + 'static> { /* fields omitted */ }

An error with context around it.

The context is intended to be a human-readable, user-facing explanation for the error that has occurred. The underlying error is not assumed to be end-user-relevant information.

The Display impl for Context only prints the human-readable context, while the Debug impl also prints the underlying error.


impl<D: Display + Send + Sync + 'static> Context<D>[src]

pub fn new(context: D) -> Context<D>[src]

Creates a new context without an underlying error message.

pub fn get_context(&self) -> &D[src]

Returns a reference to the context provided with this error.

pub fn map<F, T>(self, op: F) -> Context<T> where
    F: FnOnce(D) -> T,
    T: Display + Send + Sync + 'static, 

Maps Context<D> to Context<T> by applying a function to the contained context.
