Trait dangerous::error::Backtrace [−][src]
pub trait Backtrace: 'static {
fn root(&self) -> CoreContext;
fn count(&self) -> usize;
fn walk<'a>(&'a self, f: &mut BacktraceWalker<'a>) -> bool;
}Expand description
Implemented for walkable stacks of Contexts collected from an error.
Required methods
fn root(&self) -> CoreContext[src]
fn root(&self) -> CoreContext[src]The root context.
fn walk<'a>(&'a self, f: &mut BacktraceWalker<'a>) -> bool[src]
fn walk<'a>(&'a self, f: &mut BacktraceWalker<'a>) -> bool[src]Walk the context backtrace, starting with the highest context to the root.
Returns true if all of the stack available was walked, false if not.
