Struct noise::Cache

pub struct Cache<Source> {
    pub source: Source,
    /* private fields */
}

Noise function that caches the last output value generated by the source function.

If the input coordinates passed to Cache::get are equal to the previous call, the function returns the cached result of the previous call to Source::get. Otherwise, Source::get is called with the new coordinates, overwriting the cache with the result, and returning the result to the caller.

Caching a noise function is useful if it is used as a source function for multiple noise functions. If a source function is not cached, the source function will redundantly calculate the same output value once for each noise function in which it is included.

Fields

source: Source

Outputs the value to be cached.
