Expand description
This defines a BigInteger, a smart wrapper around a
sequence of u64 limbs, least-significant limb first.
Associated Constants
Required methods
fn add_nocarry(&mut self, other: &Self) -> bool[src]
fn add_nocarry(&mut self, other: &Self) -> bool[src]Add another representation to this one, returning the carry bit.
fn sub_noborrow(&mut self, other: &Self) -> bool[src]
fn sub_noborrow(&mut self, other: &Self) -> bool[src]Subtract another representation from this one, returning the borrow bit.
Performs a leftwise bitshift of this number, effectively multiplying it by 2. Overflow is ignored.
Compute the number of bits needed to encode this number. Always a multiple of 64.
fn from_bits_be(bits: &[bool]) -> Self[src]
fn from_bits_be(bits: &[bool]) -> Self[src]Returns the big integer representation of a given big endian boolean array.
fn from_bits_le(bits: &[bool]) -> Self[src]
fn from_bits_le(bits: &[bool]) -> Self[src]Returns the big integer representation of a given little endian boolean array.
fn to_bytes_be(&self) -> Vec<u8>[src]
fn to_bytes_be(&self) -> Vec<u8>[src]Returns the byte representation in a big endian byte array, with leading zeros.
fn to_bytes_le(&self) -> Vec<u8>[src]
fn to_bytes_le(&self) -> Vec<u8>[src]Returns the byte representation in a little endian byte array, with trailing zeros.
Provided methods
fn to_bits_be(&self) -> Vec<bool>[src]
fn to_bits_be(&self) -> Vec<bool>[src]Returns the bit representation in a big endian boolean array, with leading zeroes.
fn to_bits_le(&self) -> Vec<bool>[src]
fn to_bits_le(&self) -> Vec<bool>[src]Returns the bit representation in a little endian boolean array, with trailing zeroes.
Returns the windowed non-adjacent form of self, for a window of size w.
Writes this BigInteger as a big endian integer. Always writes
(num_bits / 8) bytes.
