Enum nom::IResult [−] [src]

pub enum IResult<'a, I, O> {
    Done(I, O),
    Error(Err<'a>),
    Incomplete(Needed),
}

Holds the result of parsing functions

It depends on I, the input types, and O, the output type.

  • Done indicates a correct parsing, the first field containing the rest of the unparsed data, the second field contains the parsed data

  • Error is currently a u32, but should be updated to indicate which parser had a problem, a description, and an eventual stack of parser to know which path failed

  • Incomplete will hold the closure used to restart the computation once more data is available. Current attemps at implementation of Incomplete are progressing, but slowed down by lifetime problems
