Struct bitmac::resizing_strategy::FixedStrategy

#[repr(transparent)]
pub struct FixedStrategy(pub usize);

Increases the size of the container in a fixed increment.

Example:

use bitmac::resizing_strategy::{ResizingStrategy, FixedStrategy, MinimumRequiredLength};
let mut s = FixedStrategy(3);
assert_eq!(s.try_resize(MinimumRequiredLength::new_unchecked(1), 0, 0).unwrap().value(), 3);
assert_eq!(s.try_resize(MinimumRequiredLength::new_unchecked(2), 0, 10).unwrap().value(), 3);
assert_eq!(s.try_resize(MinimumRequiredLength::new_unchecked(3), 0, 23).unwrap().value(), 3);
assert_eq!(s.try_resize(MinimumRequiredLength::new_unchecked(4), 3, 24).unwrap().value(), 6);
assert_eq!(s.try_resize(MinimumRequiredLength::new_unchecked(5), 3, 35).unwrap().value(), 6);
assert_eq!(s.try_resize(MinimumRequiredLength::new_unchecked(6), 3, 47).unwrap().value(), 6);

Trait Implementations

impl Clone for FixedStrategy

fn clone(&self) -> FixedStrategy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FixedStrategy

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

Formats the value using the given formatter.

impl Hash for FixedStrategy

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, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<FixedStrategy> for FixedStrategy

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

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

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

This method tests for !=.

impl ResizingStrategy for FixedStrategy

fn try_resize(
    &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 try_resize_opt(
    &mut self,
    _min_req_len: MinimumRequiredLength,
    _old_len: usize,
    _bit_idx: usize
) -> Result<Option<FinalLength>, ResizeError>

Will be called when a bitmap needs to resize its container to put a value, but new bit value is 0 (false), which means container resizing is optional.
