Struct Stack 

pub struct Stack { /* private fields */ }

A walk, innermost first. Never empty: the frame it was taken in is always one of them, and a walk that reaches no frame is refused where it is read.

One array in JSON, and one field wherever an instrument reports where it was. Which frame is the call site is top, not a second field beside the rest.

Implementations

impl Stack

pub fn of(frames: Vec<Frame>) -> Option<Self>

None for no frames at all, which is not a walk.

pub fn top(&self) -> &Frame

The frame the walk was taken in.

pub fn below(&self) -> &[Frame]

The frames above it, outermost last.

pub fn frames(&self) -> impl Iterator<Item = &Frame>
