Struct orx_split_vec::LinearGrowth

pub struct LinearGrowth;

Stategy which allows the split vector to grow linearly.

In other words, each new fragment will have equal capacity, which is equal to the capacity of the first fragment.

Examples

use orx_split_vec::prelude::*;

// SplitVec<usize, LinearGrowth>
let mut vec = SplitVec::with_linear_growth(16);

assert_eq!(1, vec.fragments().len());
assert_eq!(Some(16), vec.fragments().first().map(|f| f.capacity()));
assert_eq!(Some(0), vec.fragments().first().map(|f| f.len()));

// push 160 elements
for i in 0..10 * 16 {
    vec.push(i);
}

assert_eq!(10, vec.fragments().len());
for fragment in vec.fragments() {
    assert_eq!(16, fragment.len());
    assert_eq!(16, fragment.capacity());
}

// push the 161-st element
vec.push(42);
assert_eq!(11, vec.fragments().len());
assert_eq!(Some(16), vec.fragments().last().map(|f| f.capacity()));
assert_eq!(Some(1), vec.fragments().last().map(|f| f.len()));

Trait Implementations

impl Clone for LinearGrowth

fn clone(&self) -> LinearGrowth

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LinearGrowth

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LinearGrowth

fn default() -> LinearGrowth

Returns the “default value” for a type.

impl PartialEq<LinearGrowth> for LinearGrowth

fn eq(&self, other: &LinearGrowth) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> SplitVecGrowth<T> for LinearGrowth

fn new_fragment_capacity(&self, fragments: &[Fragment<T>]) -> usize

Given that the split vector contains the given fragments, returns the capacity of the next fragment.

fn get_fragment_and_inner_indices( &self, fragments: &[Fragment<T>], element_index: usize ) -> Option<(usize, usize)>

Returns the location of the element with the given element_index on the split vector as a tuple of (fragment-index, index-within-fragment).
