Struct ParserState

pub struct ParserState { /* private fields */ }

Opaque state for pausing and resuming a parse.

When a visitor returns ControlFlow::Break, the parser yields a ParserState. Pass that state and the same visitor to resume to continue from the next block. The state is only valid for the same src slice and visitor; do not modify src between pause and resume.

Implementations

impl ParserState

pub const fn empty() -> Self

State for starting a parse from the beginning of src.

Trait Implementations

impl Clone for ParserState

fn clone(&self) -> ParserState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParserState

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

Formats the value using the given formatter.

impl Default for ParserState

fn default() -> Self

Returns the “default value” for a type.

impl Hash for ParserState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ParserState

fn eq(&self, other: &ParserState) -> 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.
