Struct ForceGrowStrategy 

pub struct ForceGrowStrategy<S>(pub S);

Increases the size of the container despite new bit state is 0 (false). In other words is_force_grow() always returns true.

Example:

use bitmac::grow_strategy::{GrowStrategy, MinimumRequiredStrategy, ForceGrowStrategy, MinimumRequiredLength};
let mut s = ForceGrowStrategy(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!(s.is_force_grow());

Trait Implementations

impl<S: Clone> Clone for ForceGrowStrategy<S>

fn clone(&self) -> ForceGrowStrategy<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for ForceGrowStrategy<S>

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

Formats the value using the given formatter.

impl<S> GrowStrategy for ForceGrowStrategy<S>

where S: GrowStrategy,

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<S: Hash> Hash for ForceGrowStrategy<S>

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<S: PartialEq> PartialEq for ForceGrowStrategy<S>

fn eq(&self, other: &ForceGrowStrategy<S>) -> 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.

impl<S: Copy> Copy for ForceGrowStrategy<S>

impl<S: Eq> Eq for ForceGrowStrategy<S>

impl<S> StructuralPartialEq for ForceGrowStrategy<S>
