Struct Checkpoint 

pub struct Checkpoint { /* private fields */ }

A lightweight snapshot of StrStack state for checkpoint/rollback.

Created by StrStack::checkpoint, consumed by StrStack::reset. Fields are private to preserve the invariant that bytes always points to a valid UTF-8 boundary within data.

impl Clone for Checkpoint

fn clone(&self) -> Checkpoint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Checkpoint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Checkpoint

fn eq(&self, other: &Checkpoint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
