//! Mutable objects with each field being separately allocated and changeable.
//!
//! Mutable objects are Commits, Trees, Blobs and Tags that can be changed and serialized.
//! They either created using object [construction][Object] or by [deserializing existing objects][crate::immutable::Object::from_bytes()]
//! and converting these [into mutable copies][crate::immutable::Object::into_mutable()] for adjustments.
