Struct iodyn::raz_meta::Count

pub struct Count(pub usize);

Meta data for element count and positioning from the left

usize::max_value() is a special marker for the end of the sequence, otherwise, values too large will fail in some appropriate way.

Trait Implementations

impl Clone for Count

fn clone(&self) -> Count

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for Count

impl PartialEq for Count

fn eq(&self, __arg_0: &Count) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Count) -> bool

This method tests for !=.

impl Hash for Count

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Debug for Count

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<E> RazMeta<E> for Count

type Index = usize

fn from_none(_lev: u32, _n: Option<Name>) -> Self

create meta data for an empty branch

fn from_vec(vec: &Vec<E>, _lev: u32, _n: Option<Name>) -> Self

create meta data from a leaf vec

fn from_meta(Count: &Self, Count: &Self, _l: u32, _n: Option<Name>) -> Self

create meta data from the pair of meta data in branches

fn navigate(
    Count: &Self,
    Count: &Self,
    index: &Self::Index
) -> Navigation<Self::Index>

choose a branch and create an adjusted index for that branch

fn split_vec<'a>(vec: &'a Vec<E>, index: &Self::Index) -> (&'a [E], &'a [E])

Panics

Panics if the index is too high
