[][src]Struct read_token::ReadToken

pub struct ReadToken<'a> {
    pub src: &'a str,
    pub offset: usize,

Stores the state of parsing.


src: &'a str


offset: usize

Byte offset.


impl<'a> ReadToken<'a>[src]

pub fn new(src: &'a str, offset: usize) -> ReadToken<'a>[src]

Creates a new ReadToken. The offset is in bytes.

pub fn consume(self, n: usize) -> ReadToken<'a>[src]

Consumes n bytes.

pub fn raw_string(&self, n: usize) -> String[src]

Reads a raw string.

pub fn lines<F>(&self, f: F) -> Result<Range, Range> where
    F: FnMut(&ReadToken) -> Option<Range>, 

Read lines until closure returns None. Returns Ok(range) of the successful read lines. Returns Err(range) when expected new line.

pub fn subtract(&self, rhs: &Self) -> Range[src]

Returns the difference in offset.

pub fn start(&self) -> Range[src]

Returns an empty range at current offset.

pub fn peek(&self, n: usize) -> Range[src]

Peek a number of bytes ahead.

pub fn tag(&self, tag: &str) -> Option<Range>[src]

Reads an expected tag, returns character range and new state. Returns old state when fail to match tag.

pub fn until_any_or_whitespace(&self, any: &str) -> (Range, Option<usize>)[src]

Reads a token until any character in string or whitespace. Returns (range, None) if stopping at whitespace or end of text. Returns (range, Some(x)) if stopping at a character.

pub fn until_any(&self, any: &str) -> (Range, Option<usize>)[src]

Reads token until any character in string. Returns (new_state, range, None) if stopping at end of text. Returns (new_state, range, Some(x)) if stopping at a character.

pub fn whitespace(&self) -> Range[src]

Reads whitespace.

pub fn string(&self) -> Option<Range>[src]

Reads string with character escapes.

pub fn number(&self, settings: &NumberSettings) -> Option<Range>[src]

Reads number.

pub fn parse_string(&self, n: usize) -> Result<String, Range<ParseStringError>>[src]

Parses string into a real string according to the JSON standard.

Assumes the string starts and ends with double-quotes. n is the number of bytes to read and must be at least 2, because the string is surrounded by quotes.

pub fn parse_number(
    settings: &NumberSettings,
    n: usize
) -> Result<f64, ParseNumberError>

Parses number from n bytes.
