Crate devela

Development extensions for the Rust Standard Library.

Features

• std (default): enables functionality that depends on the standard library. Disabling it makes the crate no_std compatible.
• alloc: enables functionality that depends on allocation. Included in std.
• no-std: enables functionality incompatible with std (unused).

---

• safe: forbids all unsafe code at the crate level.
• unsafe: meta feature enabling every modular unsafe feature:
  • unsafe_cmp: enables const floating-point comparison in cmp, using transmute for constant access to the bits.
  • unsafe_convert: enables using MaybeUninit for array initialization in slice_into_array.
  • unsafe_fmt: provides IntBuf and IntBufable in fmt. Unsafe blocks are ported verbatim from itoa.
  • unsafe_num: enables new_unchecked and implements bytemuck traits for new types defined in num.

---

• bytemuck: implements several unsafe bytemuck traits for num types.
