Enum combine::easy::Error [−][src]
pub enum Error<T, R> { Unexpected(Info<T, R>), Expected(Info<T, R>), Message(Info<T, R>), Other(Box<dyn StdError + Send + Sync>), }
Expand description
Enum used to store information about an error that has occurred during parsing.
Variants
Unexpected(Info<T, R>)
Error indicating an unexpected token has been encountered in the stream
Expected(Info<T, R>)
Error indicating that the parser expected something else
Message(Info<T, R>)
Generic message
Variant for containing other types of errors
Implementations
Returns the end_of_input
error.
Formats a slice of errors in a human readable way.
let input = r" ,123 "; let result = spaces().silent().with(char('.').or(char('a')).or(digit())) .easy_parse(position::Stream::new(input)); let m = format!("{}", result.unwrap_err()); let expected = r"Parse error at line: 2, column: 3 Unexpected `,` Expected `.`, `a` or `digit` "; assert_eq!(m, expected);
Trait Implementations
type StreamError = Self
Creates a ParseError
from a single Self::StreamError
Sets the position of this ParseError
Adds a StreamError
to self
. Read more
fn set_expected<F>(self_: &mut Tracked<Self>, info: Self::StreamError, f: F) where
F: FnOnce(&mut Tracked<Self>),
fn set_expected<F>(self_: &mut Tracked<Self>, info: Self::StreamError, f: F) where
F: FnOnce(&mut Tracked<Self>),
Sets info
as the only Expected
error of self
Does a best-effort conversion of self
into another ParseError
Merges two errors. If they exist at the same position the errors of other
are
added to self
(using the semantics of add
). If they are not at the same
position the error furthest ahead are returned, ignoring the other ParseError

Removes any expected errors currently in self
