Struct ContextStack 

pub struct ContextStack { /* private fields */ }

A stack-allocated collection of error contexts.

Note: Capacity is limited to 3 contexts. Additional contexts are silently ignored. This is a deliberate trade-off for performance in the hot parsing path.

Implementations

impl ContextStack

pub fn new() -> Self

pub fn push(&mut self, context: &'static str)

pub fn last(&self) -> Option<&&'static str>

pub fn to_vec(&self) -> Vec<&'static str>

Trait Implementations

impl Clone for ContextStack

fn clone(&self) -> ContextStack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContextStack

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

Formats the value using the given formatter.

impl Default for ContextStack

fn default() -> ContextStack

Returns the “default value” for a type.

impl PartialEq for ContextStack

fn eq(&self, other: &ContextStack) -> 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.
