Enum GraphWeightPolicy 

pub enum GraphWeightPolicy {
    Ignored,
    Optional,
    Required,
}

Weight-column policy for a graph algorithm.

Variants

Ignored

A bound weight column is accepted as graph-construction metadata but is ignored by the algorithm’s current semantic result.

Optional

A bound weight column is optional and changes algorithm results when present.

Required

A bound weight column is required for semantically valid execution.

Implementations

impl GraphWeightPolicy

pub const fn consumes_weight(self) -> bool

Whether this policy means the native executor consumes weights as an algorithm input when a weight column is bound.

pub const fn requires_weight(self) -> bool

Whether a weight column is mandatory for this algorithm.
