Enum `Needed`

pub enum Needed

Contains information on needed data if a parser returned Incomplete

Variants

Unknown: Needs more data, but we do not know how much
Size(NonZeroUsize): Contains the required data size in bytes

Implementations

`impl Needed`

fn new(s: usize) -> Self: Creates Needed instance, returns Needed::Unknown if the argument is zero
fn is_known(&self) -> bool: Indicates if we know how many bytes we need
fn map<F: Fn(NonZeroUsize) -> usize>(self, f: F) -> Needed: Maps a Needed to Needed by applying a function to a contained Size value.
