OperatorGrammar

harn_parser::operators

Struct OperatorGrammar

pub struct OperatorGrammar { /* private fields */ }

Expand description

A precedence ladder the parser climbs. Self::CURRENT is the language; Self::LEGACY reproduces the pre-0.11 operator grammar (?? between additive and multiplicative, a to b [exclusive] ranges just above |>) and exists only so harn fix --migrate-operator-syntax can read old source.

Implementations§

impl OperatorGrammar

pub const CURRENT: OperatorGrammar

pub const LEGACY: OperatorGrammar

pub fn loosest(self) -> Precedence

pub fn tighter(self, group: Precedence) -> Precedence

The group one step tighter than group on this ladder.

pub fn legacy_ranges(self) -> bool

Whether this grammar spells ranges a to b [exclusive].

fn fg(&self, value: Color) -> Painted<&T>

Returns a styled value derived from self with the foreground set to value.

This method should be used rarely. Instead, prefer to use color-specific builder methods like red() and green(), which have the same functionality but are pithier.
