Struct MinimumRequiredStrategy 

pub struct MinimumRequiredStrategy;

Increases the size of the container to the minimum required size.

Example:

use bitmac::grow_strategy::{GrowStrategy, MinimumRequiredStrategy, MinimumRequiredLength};
let mut s = MinimumRequiredStrategy;
assert_eq!(s.try_grow(MinimumRequiredLength::new_unchecked(1), 0, 0).unwrap().value(), 1);
assert_eq!(s.try_grow(MinimumRequiredLength::new_unchecked(2), 0, 10).unwrap().value(), 2);
assert_eq!(s.try_grow(MinimumRequiredLength::new_unchecked(3), 0, 23).unwrap().value(), 3);
assert_eq!(s.try_grow(MinimumRequiredLength::new_unchecked(4), 3, 24).unwrap().value(), 4);
assert_eq!(s.try_grow(MinimumRequiredLength::new_unchecked(5), 3, 35).unwrap().value(), 5);
assert_eq!(s.try_grow(MinimumRequiredLength::new_unchecked(6), 3, 47).unwrap().value(), 6);
assert!(!s.is_force_grow());

Trait Implementations

impl Clone for MinimumRequiredStrategy

fn clone(&self) -> MinimumRequiredStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MinimumRequiredStrategy

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

Formats the value using the given formatter.

impl Default for MinimumRequiredStrategy

fn default() -> MinimumRequiredStrategy

Returns the “default value” for a type.

impl GrowStrategy for MinimumRequiredStrategy

fn try_grow( &mut self, min_req_len: MinimumRequiredLength, _old_len: usize, _bit_idx: usize, ) -> Result<FinalLength, ResizeError>

Will be called when the bitmap needs to extend its container. New length always >= minimal required length of container.

fn is_force_grow(&self) -> bool

Checks if the container should grow if the changing bit is exceeding container’s length and its new state is 0 (false)

impl Hash for MinimumRequiredStrategy

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MinimumRequiredStrategy

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

Tests for self and other values to be equal, and is used by ==.

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

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