A Rust crate that provides bit-addressed memory management, specializing slices, arrays, and vectors to store one bit per bool, similar to C++'s std::bitset and std::vector<bool>. It also supports dividing memory into arbitrary-width integer regions like Erlang binaries, with safe concurrent aliasing semantics.

Use cases

• store booleans compactly one bit per bool in Rust
• implement bitfields for wire protocols and binary formats
• parse and build bit-level data streams like Erlang binaries
• manipulate individual bits without manual shift and mask code
• use bitsets and bitvectors with Rust ownership and borrowing
• work with bit-addressed memory in embedded Rust projects

When to choose

• you need safe, idiomatic Rust bit-level memory access with precise layout control
• you want C++ std::bitset or vector<bool> equivalents in Rust
• you need bitfield packing for transport protocols or binary serialization
• you require concurrent-safe bit slice aliasing

When to avoid

• you only need simple integer bitmask math on a handful of flags
• you are not working in Rust
• you need a bit-level binary parser DSL rather than a memory model (consider deku)
