Struct ErrToken 

pub struct ErrToken(/* private fields */);

ZST used to ensure that Parser implementations push errors to ParseState.

Parser implementation must acquire an ErrToken to return ParserResult::Err, which can only be done by calling ParseState::error or by propagating an ErrToken returned by a child parser.

Trait Implementations

impl Debug for ErrToken

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

Formats the value using the given formatter.

impl PartialEq for ErrToken

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