Struct RuleList 

pub struct RuleList { /* private fields */ }

A preset’s rule list, compiled: one to MAX_RULES rules in a fixed array, so the config stays Copy and nothing per frame allocates.

Implementations

impl RuleList

pub fn one(rule: Rule) -> Self

A list of rule alone.

pub fn new(rules: &[Rule]) -> Option<Self>

rules as a list, or None when it is empty or longer than MAX_RULES.

pub fn len(&self) -> usize

How many rules the list holds, at least one.

pub fn is_empty(&self) -> bool

Never true: a list holds at least one rule. Present for the len convention.

pub fn first(&self) -> Rule

The list’s first rule.

pub fn pick(&self, index: f32) -> Rule

The rule a bound rule index of index picks: rounded, held inside the list, and the first rule where it is not finite. The engine has already rounded a structural value, so the round here only matters to a caller that has not.

Trait Implementations

impl Clone for RuleList

fn clone(&self) -> RuleList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuleList

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

Formats the value using the given formatter.

impl Default for RuleList

fn default() -> Self

DEFAULT_RULE alone — what an absent rules key means.

impl PartialEq for RuleList

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