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

Creates a contiguous bitmask for the given range by validating the range at runtime.

genmask_checked_u32

Creates a contiguous bitmask for the given range by validating the range at runtime.

genmask_checked_u64

Creates a contiguous bitmask for the given range by validating the range at runtime.

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

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

genmask_u32

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

genmask_u64

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