Struct noise::Cache

pub struct Cache<Source, T> where
    T: Float,  {
    pub source: Source,
    // some fields omitted
}

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

If the input coordinates passed to Cache::get are equal to the previous call, the module 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 module is useful if it is used as a source module for multiple noise modules. If a source module is not cached, the source module will redundantly calculate the same output value once for each noise module in which it is included.

Fields

source: Source

Outputs the value to be cached.

Methods

impl<Source, T> Cache<Source, T> where
