Enum nom::Needed

pub enum Needed {
    Unknown,
    Size(usize),
}

Contains information on needed data if a parser returned Incomplete

Variants

Unknown

needs more data, but we do not know how much

Size(usize)

contains the required data size

impl Needed

pub fn is_known(&self) -> bool

indicates if we know how many bytes we need

pub fn map<F: Fn(usize) -> usize>(self, f: F) -> Needed

Maps a Needed to Needed by applying a function to a contained Size value.
