The 16-bit signed integer type.
Implementations§
source§impl i16
impl i16
sourcepub fn from_str_radix(src: &str, radix: u32) -> Result<i16, ParseIntError>
pub fn from_str_radix(src: &str, radix: u32) -> Result<i16, ParseIntError>
Converts a string slice in a given base to an integer.
The string is expected to be an optional +
or -
sign followed by digits.
Leading and trailing whitespace represent an error. Digits are a subset of these characters,
depending on radix
:
0-9
a-z
A-Z
§Panics
This function panics if radix
is not in the range from 2 to 36.
§Examples
Basic usage:
assert_eq!(i16::from_str_radix("A", 16), Ok(10));
Runconst: 1.32.0 · sourcepub const fn count_ones(self) -> u32

pub const fn count_zeros(self) -> u32
const: 1.32.0 · 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
.
Depending on what you’re doing with the value, you might also be interested in the
ilog2
function which returns a consistent number, even if the type widens.
§Examples
Basic usage:
let n = -1i16;
assert_eq!(n.leading_zeros(), 0);

1.37.0 (const: 1.37.0) · sourcepub const fn reverse_bits(self) -> i16
pub const fn reverse_bits(self) -> i16
Reverses the order of bits in the integer. The least significant bit becomes the most significant bit, second least-significant bit becomes second most-significant bit, etc.
§Examples
Basic usage:
let n = 0x1234i16;
let m = n.reverse_bits();
assert_eq!(m, 0x2c48);

Runconst: 1.32.0 · sourcepub const fn from_le(x: i16) -> i16
pub const fn from_le(x: i16) -> i16
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.
§Examples
Basic usage:
let n = 0x1Ai16;
if cfg!(target_endian = "little") {
assert_eq!(i16::from_le(n), n)
} else {
assert_eq!(i16::from_le(n), n.swap_bytes())

pub const fn to_ne_bytes(self) -> [u8; 2]
Return the memory representation of this integer as a byte array in native byte order.
As the target platform’s native endianness is used, portable code
should use to_be_bytes
or to_le_bytes
, as appropriate,
instead.
§Examples
let bytes = 0x1234i16.to_ne_bytes();
assert_eq!(
bytes,
if cfg!(target_endian = "big") {
[0x12, 0x34]
} else {

}
);

pub const fn from_be_bytes(bytes: [u8; 2]) -> i16
Create an integer value from its representation as a byte array in big endian.
§Examples
let value = i16::from_be_bytes([0x12, 0x34]);
assert_eq!(value, 0x1234);
RunWhen starting from a slice rather than an array, fallible conversion APIs can be used:
fn read_be_i16(input: &mut &[u8]) -> i16 {
let (int_bytes, rest) = input.split_at(std::mem::size_of::<i16>());
*input = rest;
i16::from_be_bytes(int_bytes.try_into().unwrap())
}

pub const fn from_le_bytes(bytes: [u8; 2]) -> i16
Create an integer value from its representation as a byte array in little endian.
§Examples
let value = i16::from_le_bytes([0x34, 0x12]);
assert_eq!(value, 0x1234);
RunWhen starting from a slice rather than an array, fallible conversion APIs can be used:
