Struct gobble::reader::Escape

pub struct Escape { /* fields omitted */ }

A reader for strings, that allows escaping one char and mapping to another char. The returned string has already had the escape replace done

Implementations

impl Escape

pub fn e_map(self, f: char, t: char) -> Self

Add a character to the map, in a builder pattern way.

use gobble::*;
let s = tag("\"").ig_then(esc('\"','\\')
    .e_map('t','\t').e_map('p','$'))
    .parse_s(r#""my \t \pstring""#).unwrap();
assert_eq!(s,"my \t $string")

Trait Implementations

impl Clone for Escape

fn clone(&self) -> Escape

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Parser<String> for Escape

fn parse<'a>(&self, i: &LCChars<'a>) -> ParseRes<'a, String>

fn parse_s(&self, s: &str) -> Result<V, ParseError>

fn parse_sn<'a>(&self, s: &'a str) -> Result<(&'a str, V), ParseError>

fn then<P: Parser<V2>, V2>(self, p: P) -> Then<Self, P>

returns a parser that will combine the results of this and the given parser into a tuple

fn then_ig<P: Parser<V2>, V2>(self, p: P) -> ThenIg<Self, P, V, V2>

returns a Parser that will require the given parser completes, but ignores its result useful for dropping brackets and whitespace

fn ig_then<P: Parser<V2>, V2>(self, p: P) -> IgThen<Self, P, V, V2>

returns a Parser that will require this parser completes, but only return the result of the given parser useful for dropping brackets and whitespace etc

fn or<P: Parser<V>>(self, p: P) -> Or<Self, P>

Returns a Parser that will try both child parsers, (A first) and return the first successfl result

fn map<F: Fn(V) -> V2, V2>(self, f: F) -> Map<Self, V, V2, F>

Returns a Parser that converts the result of a successful parse to a different type. Much like map on iterators and Result

fn try_map<F: Fn(V) -> Result<V2, ECode>, V2>(
    self,
    f: F
) -> TryMap<Self, V, V2, F>

Returns a Parser that converts the result of a successful parse to a different type. however the map function can fail and return a result The Error type should be err::ECode, this does not have line associated. That will be attacked by the TryMap object so this will pass that error up correctly

fn asv<R: Clone>(self, r: R) -> As<Self, V, R>

fn map_err<F: Fn(ECode) -> ECode>(self, f: F) -> MapErr<Self, V, F>

fn brk(self) -> Break<Self, V>
