Trait Implementations

impl<'a> Debug for SpannedError<'a>

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

Formats the value using the given formatter.

impl<'a> ParseError<LocatedSpan<&'a str, ()>> for SpannedError<'a>

fn from_error_kind(input: Span<'a>, kind: ErrorKind) -> Self

creates an error from the input position and an ErrorKind

fn append(_: Span<'a>, _: ErrorKind, other: Self) -> Self

combines an existing error with a new one created from the input position and an ErrorKind. This is useful when backtracking through a parse tree, accumulating error context on the way

fn add_context(input: Span<'a>, ctx: &'static str, other: Self) -> Self

create a new error from an input position, a static string and an existing error. This is used mainly in the context combinator, to add user friendly information to errors when backtracking through a parse tree

fn from_char(input: I, char) -> Self

creates an error from an input position and an expected character

fn or(self, other: Self) -> Self

combines two existing error. This function is used to compare errors generated in various branches of [alt]
