Struct Parameter 

pub struct Parameter {
    pub min: i64,
    pub max: i64,
}

A parameter range for biome matching.

Represents a range [min, max] that a climate parameter can match. A point matches if it falls within this range; distance is 0 inside and increases linearly outside.

Fields

min: i64

Minimum value (quantized)

max: i64

Maximum value (quantized)

Implementations

impl Parameter

pub const fn new(min: i64, max: i64) -> Self

Create a new parameter range.

pub fn point(value: f32) -> Self

Create a point parameter (min == max).

pub fn span(min: f32, max: f32) -> Self

Create a parameter span from float values.

pub const fn span_params(min: &Parameter, max: &Parameter) -> Self

Create a parameter span from two parameters.

pub const fn distance(&self, target: i64) -> i64

Calculate the distance from a target value to this parameter range.

Returns 0 if the target is within the range, otherwise the distance to the nearest edge.

pub const fn distance_param(&self, target: &Parameter) -> i64

Calculate the distance between two parameter ranges.

pub const fn span_with(&self, other: Option<&Parameter>) -> Self

Expand this parameter to include another parameter.

Trait Implementations

impl Clone for Parameter

fn clone(&self) -> Parameter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Parameter

impl Debug for Parameter

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

Formats the value using the given formatter.

impl Eq for Parameter

impl PartialEq for Parameter

fn eq(&self, other: &Parameter) -> 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.
