Enum deku::ctx::Limit

pub enum Limit<T, Predicate: FnMut(&T) -> bool> {
    Count(usize),
    Until(Predicate, PhantomData<T>),
    Bits(BitSize),
}

A limit placed on a container's elements

Variants

Count(usize)

Read a specific count of elements

Until(Predicate, PhantomData<T>)

Read until a given predicate holds true

Bits(BitSize)

Read until a given quantity of bits have been read

Implementations

impl<T, Predicate: for<'a> FnMut(&'a T) -> bool> Limit<T, Predicate>

pub fn new_until(predicate: Predicate) -> Self

Constructs a new Limit that reads until the given predicate returns true The predicate is given a reference to the latest read value and must return true to stop reading

impl<T> Limit<T, fn(_: &T) -> bool>

pub fn new_count(count: usize) -> Self

Constructs a new Limit that reads unil the given number of elements are read

pub fn new_bits(bits: BitSize) -> Self

Constructs a new Limit that reads until the given number of bits have been read
