Struct ParserRuleArg 

pub struct ParserRuleArg {
    pub source_state: usize,
    pub rule_index: usize,
    pub value: i64,
    pub inherit_local: bool,
}

Integer argument metadata for a generated parser rule invocation.

ANTLR’s serialized ATN does not retain Rust-target rule argument values, so the generator records the rule-transition source state and the value that should be visible to semantic predicates inside the callee.

Fields

source_state: usize

ATN state containing the rule transition that receives this argument.

rule_index: usize

Callee rule index for the transition.

value: i64

Literal fallback value to expose in the callee.

inherit_local: bool

Whether the callee should inherit the caller’s current integer argument.

Trait Implementations

impl Clone for ParserRuleArg

fn clone(&self) -> ParserRuleArg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParserRuleArg

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

Formats the value using the given formatter.

impl Ord for ParserRuleArg

fn cmp(&self, other: &ParserRuleArg) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ParserRuleArg

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

impl PartialOrd for ParserRuleArg

fn partial_cmp(&self, other: &ParserRuleArg) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
