Crate cache_this

Macro for simple caching of expressions using the local file system. The expression within the cache_this macro will be executed only if no cached result is already locally present. If no result is present yet it will be saved to the local file system and subsequently used.

Results are even cached in between program execution enabling rapid prototyping by getting rid of long execution times per iteration.

Expression are cache by their token representation. cache_this! does not recognize changes to expression results. To remove the cached values delete the .cache-this folder.

Note that, for serializing and deserializing cache_this! relies on serde_json. Thus, cache_this! requires to be cached expression results to implement the needed traits.

Example

/// `some_long_running_function` will be executed here once
let result = cache_this!(some_long_running_function());
///...
/// in following calls the cached result will be read without
/// executing the function
some_other_method(cache_this!(some_long_running_function()));
