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.
