fn pub write_i32(value: Int, into: mut ByteArray, at: Int) {

  (into.to_pointer as Int + at as Pointer[UInt32]).0 = value as UInt32

fn pub static write_i32(value: Int, into: mut ByteArray, at: Int)

Writes a value interpreted as a 32-bits unsigned integer into into as a series of bytes, starting at the index at.

If value is greater than the maximum value of a 32-bits unsigned integer, the additional bits are ignored (i.e. the value wraps around).

Panics

This method panics if into doesn't contain at least 4 values starting at index at.

Examples

import std.endian.little

let bytes = ByteArray.filled(with: 0, times: 4)

little.write_i32(123456789, into: bytes, at: 0)
bytes # => ByteArray.from_array([21, 205, 91, 7])
