An int-valued provider.

Mirrors vanilla’s IntProvider hierarchy used by feature placement and feature configuration data.

Variants

Constant(i32)

Always returns the same value.

Uniform

Uniform inclusive over [min_inclusive, max_inclusive].

Fields

min_inclusive: i32

Inclusive lower bound.

max_inclusive: i32

Inclusive upper bound.

BiasedToBottom

Biased toward the bottom.

Fields

min_inclusive: i32

Inclusive lower bound.

max_inclusive: i32

Inclusive upper bound.

VeryBiasedToBottom

Heavily biased toward the bottom.

Fields

min_inclusive: i32

Inclusive lower bound.

max_inclusive: i32

Inclusive upper bound.

inner: i32

Minimum span of the inner window.

Trapezoid

Sum of two uniform draws, symmetric triangle when plateau == 0.

Fields

min: i32

Lower bound.

max: i32

Upper bound.

plateau: i32

Flat-top width.

ClampedNormal

Gaussian with given mean/deviation, clamped to [min_inclusive, max_inclusive].

Fields

mean: f32

Distribution mean.

deviation: f32

Standard deviation.

min_inclusive: i32

Inclusive lower bound.

max_inclusive: i32

Inclusive upper bound.

Clamped

Clamps another provider to an inclusive range.

Fields

source: Box<IntProvider>

Source provider.

min_inclusive: i32

Inclusive lower bound.

max_inclusive: i32

Inclusive upper bound.

WeightedList

Weighted provider selection.

Fields

distribution: Vec<WeightedIntProvider>

Weighted alternatives.

Implementations

impl IntProvider

pub fn min(&self) -> i32

Static lower bound for this provider.

pub fn max(&self) -> i32

Static upper bound for this provider.

pub fn sample<R: Random + ?Sized>(&self, random: &mut R) -> i32

Sample a value.

Matches vanilla’s provider structure. Weighted-list selection is the standard total-weight draw used by vanilla’s SimpleWeightedRandomList.

Trait Implementations

impl Clone for IntProvider

fn clone(&self) -> IntProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntProvider

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IntProvider

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.
