Struct RubyBlockScope 

pub struct RubyBlockScope { /* private fields */ }

A labeled Ruby block scope targeted by break and next exits.

Lowers Ruby block control onto the control organ’s labeled-prompt contract: the scope pairs a label with the control prompt that bounds it.

Implementations

impl RubyBlockScope

pub fn new(label: Symbol) -> Self

Creates a block scope for label, deriving its control prompt.

pub fn label(&self) -> &Symbol

Returns the scope’s label.

pub fn prompt(&self) -> &Ref

Returns the control prompt that bounds this scope.

pub fn labeled_prompt(&self) -> LabeledPrompt

Returns the LabeledPrompt pairing this scope’s label and prompt.

Trait Implementations

impl Clone for RubyBlockScope

fn clone(&self) -> RubyBlockScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RubyBlockScope

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

Formats the value using the given formatter.

impl Eq for RubyBlockScope

impl PartialEq for RubyBlockScope

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