linux-toradex.git/rust/helpers/xarray.c, branch v6.17-rc3 Linux kernel for Apalis and Colibri modules rust: xarray: Add an abstraction for XArray 2025-05-01T09:37:59+00:00 Tamir Duberstein tamird@gmail.com 2025-04-23T13:54:38+00:00 210b81578efbe5c5e7748e50d313e1a90b03df55 `XArray` is an efficient sparse array of pointers. Add a Rust abstraction for this type. This implementation bounds the element type on `ForeignOwnable` and requires explicit locking for all operations. Future work may leverage RCU to enable lockless operation.

abstraction for this type.

This implementation bounds the element type on `ForeignOwnable` and
requires explicit locking for all operations. Future work may leverage
