Derive Macro bytemuck_derive::CheckedBitPattern

#[derive(CheckedBitPattern)]

Derive the CheckedBitPattern trait for a struct or enum.

The macro ensures that the type follows all the the safety requirements for the CheckedBitPattern trait and derives the required Bits type definition and is_valid_bit_pattern method for the type automatically.

The following constraints need to be satisfied for the macro to succeed:

If applied to a struct:

• All fields must implement CheckedBitPattern
• The struct must be #[repr(C)] or #[repr(transparent)]
• The struct must contain no generic parameters

If applied to an enum:

• The enum must be explicit #[repr(Int)]
• All fields in variants must implement CheckedBitPattern
• The enum must contain no generic parameters
