# Module bounded_vec

Module: `std::collections::bounded_vec`

## Structs

- [BoundedVec](/aztec-nr-api/v6.0.0/std/collections/bounded_vec/struct.BoundedVec.md): A `BoundedVec<T, MaxLen>` is a growable storage similar to a built-in vector except that it is bounded with a maximum possible length. `BoundedVec` is also not subject to the same restrictions vectors are (notably, nested vectors are disallowed).
