Crate aligned_vec

source ·
Expand description


This crate provides the AVec<T> and ABox<T> types, which are intended to have a similar API to Vec<T> and Box<T>, but align the data they contain to a runtime alignment value.

This is useful for situations where the alignment of the data matters, such as when working with numerical data that can get performance benefits from being aligned to a SIMD-compatible memory address.


  • std (default feature): Links this crate to the std-crate instead of the core-crate.
  • serde: Implements serialization and deserialization features for ABox and AVec.


  • Create a vector that is aligned to a cache line boundary.
  • Create a vector that is aligned to a runtime alignment value.


  • Aligned box. See Box for more info.
  • Aligned vector. See Vec for more info.
  • Type wrapping a compile-time alignment value.
  • Type wrapping a runtime alignment value.




  • Trait for types that wrap an alignment value.
