Module bitlen 

Bit calculations.

These provide a single place to handle bits-to-bytes conversions and the u32/usize discrepancy that can only be solved by panics or casting.

Functions

from_bytes 🔒

Calculate a u32 representing a number of bits from the given number of bytes as a usize.

from_limbs 🔒

Calculate a u32 representing a number of bits in an integer with the given number of limbs.

mul 🔒

to_bytes 🔒

Calculate a usize representing the number of bytes required to store the given number of bits represented as a u32 (i.e. rounding up).

to_limbs 🔒

Calculate a usize representing the number of limbs required to store the given number of bits represented as a u32 (i.e. rounding up).

u32_to_usize 🔒

usize_to_u32 🔒
