Enum chomp::parsers::Error
[−]
[src]
pub enum Error<I> { Expected(I), Unexpected, String(Vec<I>), }
Common error for the basic Chomp parsers, verbose version.
This is a verbose version of the common error for the basic Chomp parsers. It will contain
information about what a parser expected or if it encountered something unexpected (in the
case of user supplied predicates, eg. satisfy
).
This is coupled with the state found in the error state of the ParseResult
type.
Variants
Expected(I)
Expected a specific token
Unexpected
Did not expect the token present in the input stream
String(Vec<I>)
Expected a specific string of tokens
Methods
impl<I> Error<I>
[src]
fn new() -> Self
Creates a new Unexpected error.
Should be used when the error value is not important.
Trait Implementations
impl<I: Hash> Hash for Error<I>
[src]
fn hash<__HI: Hasher>(&self, __arg_0: &mut __HI)
Feeds this value into the state given, updating the hasher as necessary.
fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher
1.3.0
Feeds a slice of this type into the state provided.
