Core routines shared by all libraries
This crate provides a set of core routines shared
by the decoders and encoders under zune umbrella
It currently contains
- A bytestream reader and writer with endian aware reads and writes
- Colorspace and bit depth information shared by images
- Image decoder and encoder options
- A simple enum type to hold image decoding results.
This library is #[no_std] with alloc feature needed for defining Vec
which we need for storing decoded bytes.
