RuleSet

tree_morph::rule

Struct RuleSet 

Source 
pub struct RuleSet<'a, R> { /* private fields */ }
Expand description

A view into the rules applicable to a specific node, split into two slices.

universal contains rules that apply to all nodes; filtered contains rules that were prefiltered to this node’s discriminant id. Both slices are empty-or-valid references into the engine’s rule storage — no allocation is required to produce this type.

Implementations§

Source§

impl<'a, R> RuleSet<'a, R>

Source

pub fn len(&self) -> usize

Total number of rules in this set.

Source

pub fn is_empty(&self) -> bool

Returns true if there are no rules in this set.

Source

pub fn par_iter(&self) -> impl ParallelIterator<Item = &'a R>
where R: Sync,

Returns a Rayon parallel iterator over the rules in this set.

Chains the universal and filtered slices without any intermediate allocation.
