Struct combine::easy::Errors
[−]
[src]
pub struct Errors<I, R, P> {
pub position: P,
pub errors: Vec<Error<I, R>>,
}Struct which hold information about an error that occurred at a specific position.
Can hold multiple instances of Error if more that one error occurred in the same position.
Fields
position: P
The position where the error occurred
errors: Vec<Error<I, R>>
A vector containing specific information on what errors occurred at position. Usually
a fully formed message contains one Unexpected error and one or more Expected errors.
Message and Other may also appear (combine never generates these errors on its own)
and may warrant custom handling.
Methods
impl<I, R, P> Errors<I, R, P>[src]
pub fn new(position: P, error: Error<I, R>) -> Errors<I, R, P>[src]
Constructs a new ParseError which occurred at position.
pub fn empty(position: P) -> Errors<I, R, P>[src]
Constructs an error with no other information than the position it occurred at.
pub fn from_errors(position: P, errors: Vec<Error<I, R>>) -> Errors<I, R, P>[src]
Constructs a ParseError with multiple causes.
pub fn end_of_input(position: P) -> Errors<I, R, P>[src]
Constructs an end of input error. Should be returned by parsers which encounter end of input unexpectedly.
pub fn add_error(&mut self, error: Error<I, R>) where
I: PartialEq,
R: PartialEq, [src]
I: PartialEq,
R: PartialEq,
Adds an error if error does not exist in this ParseError already (as determined byte
PartialEq).
pub fn set_expected(&mut self, info: Info<I, R>)[src]
Removes all Expected errors in self and adds info instead.
pub fn merge(self, other: Errors<I, R, P>) -> Errors<I, R, P> where
P: Ord,
I: PartialEq,
R: PartialEq, [src]
P: Ord,
I: PartialEq,
R: PartialEq,
Merges two ParseErrors. If they exist at the same position the errors of other are
added to self (using add_error to skip duplicates). If they are not at the same
position the error furthest ahead are returned, ignoring the other ParseError.
pub fn map_position<F, Q>(self, f: F) -> Errors<I, R, Q> where
F: FnOnce(P) -> Q, [src]
F: FnOnce(P) -> Q,
Maps the position to a new value
pub fn map_token<F, U>(self, f: F) -> Errors<U, R, P> where
F: FnMut(I) -> U, [src]
F: FnMut(I) -> U,
Maps all token variants to a new value
pub fn map_range<F, S>(self, f: F) -> Errors<I, S, P> where
F: FnMut(R) -> S, [src]
F: FnMut(R) -> S,
Maps all range variants to a new value.

Range: PartialEq,
Position: Ord, [src]
Item: PartialEq,
Range: PartialEq,

type StreamError = Error<Item, Range>
fn empty(pos: Position) -> Self[src]
Constructs an empty error. Read more
fn from_error(position: Position, err: Self::StreamError) -> Self[src]
Creates a ParseError from a single Self::StreamError
fn set_position(&mut self, position: Position)[src]
Sets the position of this ParseError
fn merge(self, other: Self) -> Self[src]

T: ParseError<Item, Range, Position>, [src]
T: ParseError<Item, Range, Position>,
