Struct failure::Context
[−]
[src]
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.
Methods
impl<D: Display + Send + Sync + 'static> Context<D>

fn new(context: D) -> Context<D>
[src]
Create a new context without an underlying error message.
fn get_context(&self) -> &D
[src]
Returns a reference to the context provided with this error.
