fn shiftLeftSat(r: *Mutable, a: Const, shift: usize, signedness: Signedness, bit_count: usize) void
[src]
r = a <<| shift with 2s-complement saturating semantics.
r and a may alias.
Asserts there is enough memory to fit the result. The upper bound Limb count is r is calcTwosCompLimbCount(bit_count)
.
