Struct PredicateTool

pub struct PredicateTool<P> { /* private fields */ }

Tool that matches characters which satisfies the provided predicate.

See also PredicateRefTool.

Implementations

impl<P: Fn(char) -> bool> PredicateTool<P>

pub const fn new(predicate: P) -> Self

Create a new PredicateTool from a predicate.

pub const fn new_zero_or_more(predicate: P) -> RepeatTool<Self, TrueParser>

Creates a tool that matches zero or more occurrences of characters that satisfy the specified predicate.

pub const fn new_one_or_more(predicate: P) -> RepeatToolMin<Self, TrueParser>
