Struct Trace

pub struct Trace(/* private fields */);

A backtrace-like structure to store traces.

Implementations

impl Trace

pub fn new() -> Self

Create a new empty Trace.

pub fn add<D>(&mut self, trace: D)

where D: Display + Send + Sync + 'static,

Add trace.

Example

let mut trace = Trace::new();

trace.add("item 1");
trace.add("item 2");

pub fn iter(&self) -> TraceIter<'_>

Get an iterator over all traces.

The returned iterator iterates over all traces in the reverse order they were added.

Example

let mut trace = Trace::new();

trace.add("item 1");
trace.add("item 2");

let mut iter = trace.iter().map(|x| x.to_string());
assert_eq!(iter.next().as_deref(), Some("item 2"));
assert_eq!(iter.next().as_deref(), Some("item 1"));
assert_eq!(iter.next(), None);
