Functions

• bit_u8
  Computes 1 << n by performing a compile-time assertion that n is in bounds.
• bit_u16
  Computes 1 << n by performing a compile-time assertion that n is in bounds.
• bit_u32
  Computes 1 << n by performing a compile-time assertion that n is in bounds.
• bit_u64
  Computes 1 << n by performing a compile-time assertion that n is in bounds.
• checked_bit_u8
  Computes 1 << n if n is in bounds, i.e.: if n is smaller than the maximum number of bits supported by the type.
• checked_bit_u16
  Computes 1 << n if n is in bounds, i.e.: if n is smaller than the maximum number of bits supported by the type.
• checked_bit_u32
  Computes 1 << n if n is in bounds, i.e.: if n is smaller than the maximum number of bits supported by the type.
• checked_bit_u64
  Computes 1 << n if n is in bounds, i.e.: if n is smaller than the maximum number of bits supported by the type.
• genmask_checked_u8
  Creates a contiguous bitmask for the given range by validating the range at runtime.
• genmask_checked_u16

• genmask_u8
  Creates a compile-time contiguous bitmask for the given range by performing a compile-time assertion that the range is valid.
• genmask_u16
