pub struct PairUsize<T = usize> { /* private fields */ }
Expand description

A pair of PackUsizes, allowing a bit range to be unpacked from one offset in a usize value, and packed into a different offset in a different value.

See the module-level documentation for details on using packing specs.

Implementations§

source§

impl PairUsize

source

pub const fn src(&self) -> &PackUsize

Returns the “source” member of the packing pair.

source

pub const fn dst(&self) -> &PackUsize

Returns the “destination” member of the packing pair.

source

pub const fn pack_from_src(&self, src: usize, dst: usize) -> usize

Pack bits from the source location in src into the destination location in dst.

source

pub const fn pack_from_dst(&self, src: usize, dst: usize) -> usize

Pack bits from the destination location in dst into the source location in src.

source

pub fn assert_valid(&self)

Asserts that this packing pair is valid.

Because assertions cannot be made in const fn, this performs validating assertions that would ideally be made when constructing a new instance of this type. When packing specs are declared as consts, this method can be called in a unit test to ensure that the spec is valid.
