Crate icon_cache

Complete and user-friendly zero-copy wrappers for the GTK icon cache which is present on most linux systems.

GTK’s icon cache maintains a hash-indexed map from icon names (e.g. open-menu) to a list of images representing that icon, each in a different directory, usually denoting that icon’s size, whether it’s scalable, etc.

This crate provides a safe wrapper around this cache and is designed for use with mmap. To get started, look at IconCache.
