Trait Implementations

impl Clone for VttError

fn clone(&self) -> VttError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> ContextError<LocatedSpan<&'a str>> for VttError

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

Creates 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

impl Debug for VttError

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

Formats the value using the given formatter.

impl Display for VttError

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

Formats the value using the given formatter.

impl<'a> From<Err<Error<LocatedSpan<&'a str>>>> for VttError

fn from(error: Err<Error<LocatedSpan<&'a str>>>) -> Self

Converts to this type from the input type.

impl<'a> ParseError<LocatedSpan<&'a str>> for VttError

fn from_error_kind(input: LocatedSpan<&'a str>, kind: ErrorKind) -> Self

Creates an error from the input position and an ErrorKind

fn append(input: LocatedSpan<&'a str>, kind: 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 from_char(input: LocatedSpan<&'a str>, c: char) -> Self

Creates an error from an input position and an expected character

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

Combines two existing errors. This function is used to compare errors generated in various branches of alt.
