std::arrays

std::arrays defines borrowed views like Slice(T) and helpers for working with fixed arrays and slices.

Full reference: arrays.

Notes#

• Supported forms + design: a usable subset is implemented.
• Full reference: arrays

Importing#

import std::arrays;

Examples#

Example: Slice(T) + SliceIter(T)#

import std::arrays;
import std::buffer;

fn main () -> int {
  let mut buf: BufferU64 = BufferU64.init(4);
  buf.push(10);
  buf.push(11);
  buf.push(12);

  let s: std::arrays::Slice(u64) = { ptr: buf.ptr, len: buf.len() };
  let mut it = s.iter();
  let mut sum: u64 = 0;
  while true {
    let v: u64? = it.next();
    if v == None {
      break;
    }
    sum += (v ?? 0 as u64);
  }

  buf.drop();
  if sum != 33 {
    return 1;
  }
  return 0;
}
