[−][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.
Methods
impl<D: Display + Send + Sync + 'static> Context<D>
[src]
impl<D: Display + Send + Sync + 'static> Context<D>
pub fn new(context: D) -> Context<D>
[src]
pub fn new(context: D) -> Context<D>

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