Enum nom::IResult

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
