Enum nom::IResult
[−]
[src]
pub enum IResult<I, O, E = u32> {
Done(I, O),
Error(Err<I, E>),
Incomplete(Needed),
}Holds the result of parsing functions
It depends on I, the input type, O, the output type, and E, the error type (by default u32)
Variants
Done(I, O)indicates a correct parsing, the first field containing the rest of the unparsed data, the second field contains the parsed data
Error(Err<I, E>)contains a Err, an enum that can indicate an error code, a position in the input, and a pointer to another error, making a list of errors in the parsing tree
Incomplete(Needed)Incomplete contains a Needed, an enum than can represent a known quantity of input data, or unknown
Methods
impl<I, O, E> IResult<I, O, E>[src]
fn is_done(&self) -> bool
fn is_err(&self) -> bool
fn is_incomplete(&self) -> bool
fn map<N, F: FnOnce(O) -> N>(self, f: F) -> IResult<I, N, E>
Maps a IResult<I, O, E> to IResult<I, N, E> by appling a function
to a contained Done value, leaving Error and Incomplete value
untouched.
fn map_inc<F>(self, f: F) -> IResult<I, O, E> where F: FnOnce(Needed) -> Needed
Maps a IResult<I, O, E> to IResult<I, O, E> by appling a function
to a contained Incomplete value, leaving Done and Error value
untouched.
fn map_err<N, F>(self, f: F) -> IResult<I, O, N> where F: FnOnce(Err<I, E>) -> Err<I, N>
Maps a IResult<I, O, E> to IResult<I, O, N> by appling a function
to a contained Error value, leaving Done and Incomplete value
untouched.
fn unwrap(self) -> (I, O)
Unwrap the contained Done(I, O) value, or panic if the IResult is not
Done.
fn unwrap_inc(self) -> Needed
Unwrap the contained Done(I, O) value, or panic if the IResult is not
Done.
fn unwrap_err(self) -> Err<I, E>
Unwrap the contained Done(I, O) value, or panic if the IResult is not
Done.
