[−][src]Trait lyon_path::AttributeStore

pub trait AttributeStore {
    fn get(&self, id: EndpointId) -> &[f32];

    fn num_attributes(&self) -> usize;
}

Interface for objects storing custom attributes associated with endpoints.

This interface can be implemented by path objects themselves or via external data structures.

Required methods

fn get(&self, id: EndpointId) -> &[f32]

Returns the endpoint's custom attributes as a slice of 32 bits floats.

The size of the slice must be equal to the result of num_attributes().

fn num_attributes(&self) -> usize

Returns the number of float attributes per endpoint.

All endpoints must have the same number of attributes.
