Struct GreedyError

pub struct GreedyError<I, E> {
    pub errors: Vec<(I, GreedyErrorKind<E>)>,
}

This error type accumulates errors and their position when backtracking through a parse tree. This take a deepest error at alt combinator.

Fields

errors: Vec<(I, GreedyErrorKind<E>)>

list of errors accumulated by GreedyError, containing the affected part of input data, and some context

Trait Implementations

impl<I: Clone, E: Clone> Clone for GreedyError<I, E>

fn clone(&self) -> GreedyError<I, E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<I> ContextError<I> for GreedyError<I, ErrorKind>

where I: Position,

fn add_context(input: I, 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<I: Debug, E: Debug> Debug for GreedyError<I, E>

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

Formats the value using the given formatter.

impl<I> ParseError<I> for GreedyError<I, ErrorKind>

where I: Position,

fn from_error_kind(input: I, kind: ErrorKind) -> Self

Creates an error from the input position and an ErrorKind

fn append(input: I, 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: I, 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.

impl<I: PartialEq, E: PartialEq> PartialEq for GreedyError<I, E>

fn eq(&self, other: &GreedyError<I, E>) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
