zarray vs arrayvec vs uluru
Side-by-side comparison of Rust crates
48
zarray
growingv1.4.0
Cache-optimized 2D and 3D arrays using Morton order (aka Z-order) Z-indexed storage, with a convenient API for common 2D and 3D access patterns. Use of zarray in place of a Vec of Vecs often improves performance, especially for algorithms such as blurring and cellular automata.
64
arrayvec
growingv0.7.6
A vector with fixed capacity, backed by an array (it can be stored on the stack too). Implements fixed capacity ArrayVec and ArrayString.
61
uluru
growingv3.1.0
A simple, fast, LRU cache implementation
