Struct Trace

pub struct Trace { /* private fields */ }

An execution trace.

This trace is constructed by calling Trace::root with a closure, and includes all execution Trace of that closure that end in an invocation of Trace::leaf.

Implementations

impl Trace

pub fn root<F, R>(f: F) -> (R, Trace)

where F: FnOnce() -> R,

Invokes f, returning both its result and the collection of backtraces captured at each sub-invocation of Trace::leaf.

Examples found in repository

examples/inlining.rs (line 5)

fn main() {
    let (_, trace) = Trace::root(|| foo());
    println!("{trace}");
}

pub fn leaf()

If this is a sub-invocation of Trace::root, capture a backtrace.

The captured backtrace will be returned by Trace::root.

Invoking this function does nothing when it is not a sub-invocation Trace::root.

Examples found in repository

examples/inlining.rs (line 16)

fn bar() {
    Trace::leaf();
}

#[inline(always)]
fn baz() {
    Trace::leaf();
}
