Module bits

Expand description

Bitwise operations for creating tightly packed impls of SlabItem.

The functions and constants in this module are utilities to help when writing manual implementations of SlabItem.

Using these functions it’s possible to “tightly pack” struct fields.

Constants§

U8_0_BITS: The shift/mask range for the first 8 bits of a u32.
U8_1_BITS: The shift/mask range for the second 8 bits of a u32.
U8_2_BITS: The shift/mask range for the third 8 bits of a u32.
U8_3_BITS: The shift/mask range for the fourth 8 bits of a u32.
U16_0_BITS: The shift/mask range for the first 16 bits of a u32.
U16_1_BITS: The shift/mask range for the second 16 bits of a u32.

Functions§

bits: Statically define a shift/mask range as a literal range of bits.
extract: Extract the value of the bits defined by the shift/mask range.
extract_f32: Extract 32 bits of the u32 at the given index in the slab.
extract_i8: Extract 8 bits of the u32 at the given index in the slab.
extract_i16: Extract 16 bits of the u32 at the given index in the slab.
extract_i32: Extract 32 bits of the u32 at the given index in the slab.
extract_u8: Extract 8 bits of the u32 at the given index in the slab.
extract_u16: Extract 16 bits of the u32 at the given index in the slab.
extract_u32: Extract 32 bits of the u32 at the given index in the slab.
insert: Insert the value of the bits defined by the shift/mask range.
