Struct scrypto::math::bnum_integer::I768
source · #[repr(transparent)]pub struct I768(pub BInt<12>);
Expand description
Provides safe integer arithmetic.
Operations like +
, ‘-’, ‘*’, or ‘/’ sometimes produce overflow
which is detected and results in a panic, in of silently
wrapping around.
The bit length of output type will be the greater one in the math operation, and if any of the types was signed, then the resulting type will be signed too, otherwise the output type is unsigned.
The underlying value can be retrieved through the .0
index of the
I768
tuple.
§Layout
I768
will have the same methods and traits as
the built-in counterpart.

Implementations§
source§impl I768
impl I768
sourcepub const fn count_ones(self) -> u32
pub const fn count_ones(self) -> u32
Returns the number of ones in the binary representation of self
.
sourcepub const fn count_zeros(self) -> u32
pub const fn count_zeros(self) -> u32
Returns the number of zeros in the binary representation of self
.
sourcepub const fn trailing_zeros(self) -> u32
pub const fn trailing_zeros(self) -> u32
Returns the number of trailing zeros in the binary representation of self
.
sourcepub const fn swap_bytes(self) -> I768
pub const fn swap_bytes(self) -> I768
Reverses the byte order of the integer.
sourcepub const fn reverse_bits(self) -> I768
pub const fn reverse_bits(self) -> I768
Reverses the bit pattern of the integer.
sourcepub const fn leading_zeros(self) -> u32
pub const fn leading_zeros(self) -> u32
Returns the number of leading zeros in the binary representation of self
.
sourcepub const fn from_be(x: I768) -> I768
pub const fn from_be(x: I768) -> I768
Converts an integer from big endian to the target’s endianness.
On big endian this is a no-op. On little endian the bytes are swapped.
sourcepub const fn from_le(x: I768) -> I768
pub const fn from_le(x: I768) -> I768
Converts an integer from little endian to the target’s endianness.
On little endian this is a no-op. On big endian the bytes are swapped.
source§impl I768
impl I768
sourcepub fn abs(self) -> I768
pub fn abs(self) -> I768
Computes the absolute value of self
, with overflow causing panic.
The only case where such overflow can occur is when one takes the absolute value of the negative minimal value for the type this is a positive value that is too large to represent in the type. In such a case, this function panics.
sourcepub fn signum(self) -> I768
pub fn signum(self) -> I768
Returns a number representing sign of self
.
0
if the number is zero1
if the number is positive-1
if the number is negative
sourcepub fn is_positive(self) -> bool
pub fn is_positive(self) -> bool
Returns true
if self
is positive and false
if the number is zero or
negative.
sourcepub fn is_negative(self) -> bool
pub fn is_negative(self) -> bool
Returns true
if self
is negative and false
if the number is zero or
positive.
