Struct I32

#[repr(C)]
pub struct I32<E>(/* private fields */);

A type that wraps a byte array to be decoded into a i32.

The generic parameter represents the endianness used to decode the wrapped value. In case the value is expected to have fixed endianness, either BigEndian or LittleEndian types should be used, otherwise the Endian type.

Implementations

impl<E> I32<E>

pub const fn from_bytes(bytes: [u8; 4]) -> Self

Converts a byte array into a I32.

pub const fn into_bytes(self) -> [u8; 4]

Converts a I32 into a byte array.

impl I32<Endian>

pub const fn new_with_endian(value: i32, endian: Endian) -> Self

Constructs a I32 wrapper type from a i32 value using the specified endianness.

pub const fn get_with_endian(self, endian: Endian) -> i32

Extracts a i32 value from a I32 wrapper using the specified endianness.

impl<E: FixedEndian> I32<E>

pub const fn new(value: i32) -> Self

Constructs a I32 wrapper type from a i32 value using the type’s fixed endianness.

pub const fn get(self) -> i32

Extracts a i32 value from a I32 wrapper using the type’s fixed endianness.

Trait Implementations

impl<E: Clone> Clone for I32<E>

fn clone(&self) -> I32<E>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for I32<BigEndian>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Debug for I32<Endian>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Debug for I32<LittleEndian>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<E> Default for I32<E>

fn default() -> Self

Returns the “default value” for a type.

impl<E: FixedEndian> From<i32> for I32<E>

fn from(value: i32) -> Self

Converts to this type from the input type.

impl<E: Hash> Hash for I32<E>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<E: PartialEq> PartialEq for I32<E>

fn eq(&self, other: &I32<E>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
