core: Remove dangling module decls
core: Use new Cargo feature resolver, use external MacOS debug info
core: Rust docs improvements
core: Upgrade bindgen
core: Add test target to Rust
ci: build rust sources
build(core): .ARM.exidx.text.__aeabi_ui2f in t1 firmware size
It's an unwind table for softfloat function inserted by rustc, probably
can be removed to save 8 bytes:
599c58db70/link.x.in (L175-L182)
scons: Remove dead code
core: Move Rust target to build/rust
core: Replace extern with a FFI version
core: Add some explanatory Rust comments
core: Use correct path for the Rust lib
core: Remove Buffer::as_mut()
Mutable buffer access needs MP_BUFFER_WRITE flag. TBD in the Protobuf PR.
core: Improve docs for micropython::Buffer
core: Minor Rust docs changes
core: Rewrite trezor_obj_get_ll_checked
core: Fix incorrect doc comment
core: Remove cc from deps
fixup! core: Rewrite trezor_obj_get_ll_checked
core: update safety comments
