Struct TrueTool 

pub struct TrueTool;

A tool that matches the empty prefix.

Trait Implementations

impl<'a> AlwaysTool<'a> for TrueTool

fn parse_always(&self, st: View<'a>) -> (Self::Data, usize, View<'a>)

The main parsing algorithm.

fn parse_always_nodata(&self, st: View<'a>) -> ((), usize, View<'a>)

Automatically discards the generated data.

impl Clone for TrueTool

fn clone(&self) -> TrueTool

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrueTool

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

Formats the value using the given formatter.

impl Default for TrueTool

fn default() -> TrueTool

Returns the “default value” for a type.

impl PartialEq for TrueTool

fn eq(&self, other: &TrueTool) -> 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<'a> Tool<'a> for TrueTool

type Error = Infallible

Error type.

type Data = ()

Associated data type.

fn parse( &self, st: View<'a>, ) -> Result<(Self::Data, usize, View<'a>), Self::Error>

The main parsing algorithm.
