class Sprockets::Cache::FileStore

def set(key, value)

Experimental RBS support (using type sampling data from the type_fusion project). 

def set: (String key, (Hash | String) value) -> (Hash | String)

This signature was generated using 2 samples from 1 application.

Returns Object value.

value - Object value.
key - String cache key.

This API should not be used directly, but via the Cache wrapper API.

Public: Set a key and value in the cache.

  # Serialize value
  marshaled = Marshal.dump(value)
  # Compress if larger than 4KB
