Functions

`crc32`

fn (data: Bytes | Str | Vec): Int

Calculate CRC32 checksum (IEEE polynomial). Used by protocols like AWS Event Stream for integrity checks.

Example

crc32("hello")                  // 907060870
crc32(Bytes([72, 101, 108, 108, 111]))  // 907060870 (same)

// Verify message integrity
message-crc crc32(message-bytes)
eq(message-crc, expected-crc)

`from-int`

fn (value: Int, size: Int): Bytes
fn (value: Int, size: Int, endian: Str): Bytes

Convert an integer to bytes with specified size (1-8 bytes). Default is big-endian (network byte order).

Example

// Big-endian (default)
from-int(256, 2)        // Bytes([1, 0])
from-int(16, 4)         // Bytes([0, 0, 0, 16])

// Little-endian
from-int(256, 2, "le")  // Bytes([0, 1])

`to-int`

fn (bytes: Bytes): Int
fn (bytes: Bytes, endian: Str): Int

Convert bytes to a signed integer. Default is big-endian (network byte order). Supports 1-8 bytes.

Example

// Big-endian (default)
to-int(Bytes([0, 0, 0, 16]))     // 16
to-int(Bytes([0, 16]))           // 16

// Little-endian
to-int(Bytes([16, 0, 0, 0]), "le")  // 16

`to-uint`

fn (bytes: Bytes): Int
fn (bytes: Bytes, endian: Str): Int

Convert bytes to an unsigned integer. Default is big-endian. Supports 1-8 bytes. Values > i64::MAX will wrap to negative.

Example

// Unsigned interpretation
to-uint(Bytes([255, 255]))  // 65535 (not -1)

`to-vec`

fn (bytes: Bytes): Vec

Convert bytes to a vector of integers for easier manipulation.

Example

data Bytes([1, 2, 3])
to-vec(data)  // [1, 2, 3]
