[−][src]Struct failure::Context
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.
Implementations
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, [src]
F: FnOnce(D) -> T,
T: Display + Send + Sync + 'static,
Maps Context<D> to Context<T> by applying a function to the contained context.
