Struct ContextFrame 

pub struct ContextFrame {
    pub message: Cow<'static, str>,
    pub location: Option<&'static Location<'static>>,
}

One human-readable frame in a TestError’s context chain.

Frames render in the order they were added, so the chain reads from the outermost circumstance to the innermost.

Fields

The “while doing X” description.

location: Option<&'static Location<'static>>

Where the frame was attached, when known.
