Signed and unsigned integers.

Required Methods

fn min_value() -> Self

Returns the smallest value that can be represented by this numeric type.

fn max_value() -> Self

Returns the largest value that can be represented by this numeric type.

fn from_str_radix(src: &str, radix: u32) -> Result<Self, ParseIntError>

Converts a string slice in a given base to an integer.

fn count_ones(self) -> u32

Returns the number of ones in the binary representation of self.

fn count_zeros(self) -> u32

Returns the number of zeros in the binary representation of self.

fn leading_zeros(self) -> u32

Returns the number of leading zeros in the binary representation of self.

fn trailing_zeros(self) -> u32

Returns the number of trailing zeros in the binary representation of self.

fn rotate_left(self, n: u32) -> Self

Shifts the bits to the left by a specified amount, n, wrapping the truncated bits to the end of the resulting integer.

fn rotate_right(self, n: u32) -> Self

Shifts the bits to the right by a specified amount, n, wrapping the truncated bits to the beginning of the resulting integer.

fn swap_bytes(self) -> Self

Reverses the byte order of the integer.

fn from_be(x: Self) -> Self

Converts an integer from big endian to the target's endianness.

fn from_le(x: Self) -> Self

Converts an integer from little endian to the target's endianness.

fn to_be(self) -> Self

Converts self to big endian from the target's endianness.

fn to_le(self) -> Self

Converts self to little endian from the target's endianness.

fn checked_add(self, other: Self) -> Option<Self>

Checked integer addition. Computes self + other, returning None if overflow occurred.

fn checked_sub(self, other: Self) -> Option<Self>

Checked integer subtraction. Computes self - other, returning None if underflow occurred.

fn checked_mul(self, other: Self) -> Option<Self>

Checked integer multiplication. Computes self * other, returning None if underflow or overflow occurred.

fn checked_div(self, other: Self) -> Option<Self>

Checked integer division. Computes self / other, returning None if other == 0 or the operation results in underflow or overflow.

fn saturating_add(self, other: Self) -> Self

Saturating integer addition. Computes self + other, saturating at the numeric bounds instead of overflowing.

fn saturating_sub(self, other: Self) -> Self

Saturating integer subtraction. Computes self - other, saturating at the numeric bounds instead of overflowing.

fn wrapping_add(self, rhs: Self) -> Self

Wrapping (modular) addition. Computes self + other, wrapping around at the boundary of the type.

fn wrapping_sub(self, rhs: Self) -> Self

Wrapping (modular) subtraction. Computes self - other, wrapping around at the boundary of the type.

fn wrapping_mul(self, rhs: Self) -> Self

Wrapping (modular) multiplication. Computes self * other, wrapping around at the boundary of the type.

fn wrapping_div(self, rhs: Self) -> Self

Wrapping (modular) division. Computes self / other, wrapping around at the boundary of the type.

fn wrapping_rem(self, rhs: Self) -> Self

Wrapping (modular) remainder. Computes self % other, wrapping around at the boundary of the type.

fn wrapping_neg(self) -> Self

Wrapping (modular) negation. Computes `-self, wrapping around at the boundary of the type.

fn wrapping_shl(self, rhs: u32) -> Self

Panic-free bitwise shift-left; yields self << mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.

fn wrapping_shr(self, rhs: u32) -> Self

Panic-free bitwise shift-left; yields self >> mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.

fn pow(self, exp: u32) -> Self

Raises self to the power of exp, using exponentiation by squaring.
