minsize

Collections with a statically known minimum size, using const generics.

Features

  • Wrapper type around a plain standard library Vec that enforces an arbitrary minimum size
    • Special methods that simplify operations on collections that are known to be non-empty[note]
  • Ability to deref to a slice and to cheaply convert from and to an unrestricted Vec
    • All the methods provided by standard slices you already know and use remain available!

Note: Const generics support

With the basic first level of const generics support (historically known as min_const_generics), it is not possible to guarante the non-empty property for all const-generic values. This crate uses an indirection through a trait, that for now is implemented by hand for a small number of useful values. Once the necessary language features are stabilized, this list of manual implementations will be replaced with a proper blanket implementation.
