Struct ProviderNeeds 

pub struct ProviderNeeds { /* private fields */ }

What the program needs: capability ids that must all be on, and the lowest durability class.

Implementations

impl ProviderNeeds

pub fn new(ids: Vec<CapabilityId>, min_durability: Durability) -> Self

Every id in ids must be on, and durability must reach min_durability.

pub fn prefer(self, preferred: Vec<CapabilityId>) -> Self

What matters most, most important first. A preferred id never excludes a provider; it only orders the ones that qualify (sorted).

pub fn preferred(&self) -> &[CapabilityId]

The preferred ids, most important first.

pub fn ids(&self) -> &[CapabilityId]

The needed ids.

pub fn min_durability(&self) -> Durability

The lowest acceptable durability.
