Struct I64

#[repr(C, align(8))]
pub struct I64(/* private fields */);

A signed, 64-bit integer type with explicit alignment requirements

Without the explicit align representation hint, this type may have different alignment requirements on different machines. This helps to ensure that the type has a predictable layout in memory and that operations assuming a particular alignment value are sound.

Implementations

impl I64

pub const fn new(value: i64) -> Self

Creates a new I64 from a integer value.

Endianness

The newly-created instance uses the target machines native endianness by default. To create this type with an explicitly-specified endianness, use one of the specialized constructor methods.

pub const fn new_be(value: i64) -> Self

Creates a new I64 from a big endian integer value.

pub const fn new_le(value: i64) -> Self

Creates a new I64 from an integer, interpreting it as little endian byte order

pub const fn from_le_chunk(chunk: Chunk<8>) -> Self

Reads a new I64 in little endian byte order from a chunk of bytes with size 8

pub const fn from_be_chunk(chunk: Chunk<8>) -> Self

Reads a new I64 in big endian byte order from a chunk of bytes with size 8

pub const fn from_le_bytes(bytes: [u8; 8]) -> Self

Create a native endian integer value from its representation as a byte array in little endian.

pub const fn from_be_bytes(bytes: [u8; 8]) -> Self

Create a native endian integer value from its representation as a byte array in big endian.

pub const fn to_le_bytes(self) -> [u8; 8]

Return the memory representation of this integer as a byte array in little-endian byte order.

pub const fn to_be_bytes(self) -> [u8; 8]

Return the memory representation of this integer as a byte array in little-endian byte order.

pub const fn get(self, endian: Endian) -> i64

Get the i64 aligned integer in the the specified byte order.

pub const fn get_ne(self) -> i64

Get the i64 aligned integer in native-endian byte order.

This method uses the target endian value, calculated at compile time, to determine which byte order serialization variant to use.

pub const fn get_le(self) -> i64

Get the i64 aligned integer in little-endian byte order.

pub const fn get_be(self) -> i64

Get the i64 aligned integer in big-endian byte order.

impl I64

pub const fn read_aligned(bytes: &[u8], codec: Codec) -> Result<I64>

Reads an aligned I64 type from a slice of bytes using the specified endianness.
