Struct Parser

pub(super) struct Parser<'a> {
    state: &'a [u8],
}

Fields

state: &'a [u8]

Implementations

impl<'a> Parser<'a>

pub(super) fn new(input: &'a [u8]) -> Self

fn read_atomically<T, F>(&mut self, inner: F) -> Option<T>

where F: FnOnce(&mut Parser<'_>) -> Option<T>,

Run a parser, and restore the pre-parse state if it fails.

pub(super) fn parse_with<T, F>( &mut self, inner: F, kind: AddrKind, ) -> Result<T, AddrParseError>

where F: FnOnce(&mut Parser<'_>) -> Option<T>,

Run a parser, but fail if the entire input wasn’t consumed. Doesn’t run atomically.

fn peek_char(&self) -> Option<char>

Peek the next character from the input

fn read_char(&mut self) -> Option<char>

Read the next character from the input

fn read_given_char(&mut self, target: char) -> Option<()>

Read the next character from the input if it matches the target.

fn read_separator<T, F>( &mut self, sep: char, index: usize, inner: F, ) -> Option<T>

where F: FnOnce(&mut Parser<'_>) -> Option<T>,

Helper for reading separators in an indexed loop. Reads the separator character iff index > 0, then runs the parser. When used in a loop, the separator character will only be read on index > 0 (see read_ipv4_addr for an example)

fn read_number<T: ReadNumberHelper>( &mut self, radix: u32, max_digits: Option<usize>, allow_zero_prefix: bool, ) -> Option<T>

pub(super) fn read_ipv4_addr(&mut self) -> Option<Ipv4Addr>

Read an IPv4 address.

pub(super) fn read_ipv6_addr(&mut self) -> Option<Ipv6Addr>

Read an IPv6 Address.
