Struct failure::Backtrace[][src]

pub struct Backtrace { /* fields omitted */ }

A Backtrace.

This is an opaque wrapper around the backtrace provided by libbacktrace. A variety of optimizations have been performed to avoid unnecessary or ill-advised work:

Even with these optimizations, including a backtrace in your failure may not be appropriate to your use case. You are not required to put a backtrace in a custom Fail type.

Implementations

impl Backtrace[src]

pub fn new() -> Backtrace[src]

Constructs a new backtrace. This will only create a real backtrace if the crate is compiled in std mode and the RUST_BACKTRACE environmental variable is activated.

pub fn is_empty(&self) -> bool[src]

Returns true if displaying this backtrace would be an empty string.
