Type Definition dangerous::error::BacktraceWalker

type BacktraceWalker<'a> = dyn FnMut(usize, &dyn Context) -> bool + 'a;

A dynamic function for walking a context backtrace.

Returns true if the walk should continue, false if not.

Parameters

• parent depth (the parent depth of the context starting from 1).
• <context> (the context at the provided depth).

Parent depth

Contexts are returned from the top of the stack to the bottom. Child contexts will follow after a parent context and will share the same parent depth value.
