//! This crate generalises traits over the `len` and `capacity` methods found in most collections.
//!
//! Methods that are included:
//!
//! * [`capacity`]
//! * [`clear`]
//! * [`is_empty`]
//! * [`len`]
//! * [`reserve_exact`]
//! * [`reserve`]
//! * [`shrink_to_fit`]
//! * [`split_at_mut`]
//! * [`split_at`]
//! * [`split_off`]
//! * [`truncate`]
//! * [`with_capacity`]
//!
//! Additionally, the traits [`IndexRanges<Idx>`] and [`IndexRangesMut<Idx>`] are provided for
//! "consistent slicing," i.e. slicing over all range types.
//!
//! [`IndexRanges<Idx>`]: index/trait.IndexRanges.html
