Struct State 

pub(crate) struct State<'src> {
    pub(crate) numeral_mode: NumeralMode,
    pub(crate) body: &'src str,
    pub(crate) macros: TruncatableMap<SymbolName, MacroDefinition>,
}

Fields

numeral_mode: NumeralMode

body: &'src str

macros: TruncatableMap<SymbolName, MacroDefinition>

Implementations

impl<'src> State<'src>

pub(crate) fn new(body: &'src str, numeral_mode: NumeralMode) -> State<'src>

pub(crate) fn define_macro(&mut self, definition: MacroDefinition)

pub(crate) fn get_macro_definition( &self, name: &SymbolName, ) -> Option<&MacroDefinition>

pub(crate) fn macros(&self) -> &BTreeMap<SymbolName, MacroDefinition>

Trait Implementations

impl<'src> Clone for State<'src>

fn clone(&self) -> State<'src>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for State<'src>

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

Formats the value using the given formatter.

impl<'src, I: Input<'src>> Inspector<'src, I> for State<'src>

type Checkpoint = usize

A type the Inspector can use to revert to a previous state.

fn on_token(&mut self, _: &<I as Input<'src>>::Token)

This function is called when a new token is read from the input stream.

fn on_save<'parse>(&self, _cursor: &Cursor<'src, 'parse, I>) -> Self::Checkpoint

This function is called when a combinator saves the current state of the parse.

fn on_rewind<'parse>( &mut self, marker: &Checkpoint<'src, 'parse, I, Self::Checkpoint>, )

This function is called when a combinator rewinds to an earlier state of the parser.

impl<'src> PartialEq for State<'src>

fn eq(&self, other: &State<'src>) -> 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.
