Struct Parser 

pub struct Parser { /* private fields */ }

A parser that keeps its arena between calls (the “reused” state of the parser gate): a pass over many messages grows it once.

Implementations

impl Parser

pub const fn new() -> Self

A parser with an empty arena (does not allocate).

pub fn with_capacity(nodes: usize) -> Self

A parser whose arena has room for nodes entries.

pub fn parse_cst<'p, 'src>(&'p mut self, source: &'src str) -> CstRef<'p, 'src>

Parses source into a lossless CST held in this parser’s arena.

pub fn parse_model<'src>(&mut self, source: &'src str) -> Parsed<'src>

See parse_model; reuses this parser’s arena.

Trait Implementations

impl Clone for Parser

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Parser

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

Formats the value using the given formatter.

impl Default for Parser

fn default() -> Self

Returns the “default value” for a type.

impl Frontend for Parser

fn parse<'src>(&mut self, source: &'src str) -> Parsed<'src>

&mut self lets an implementation keep scratch state across calls (the gate’s “reused” rows); the returned model borrows only the source.
