I spoke too soon, it appears Zig's default return type for its
`len()` function is: `usize' - similar to Rust.
```rust
const std = @import("std");
pub fn main() !void {
const something = [_]u8{ 'a', 'b', 'c' };
std.debug.print("len: {d}\n", .{something.len}); // Len: 3
const len_type = @typeName(@TypeOf(something.len));
std.debug.print("len type: {s}\n", .{len_type}); // len type:
usize
var i: i32 = -1;
while (i <= @intCast(i32, something.len)) : (i += 1) {
std.debug.print("i: {d}\n", .{i});
}
}
```
Output:
```
len: 3
len type: usize
i: -1
i: 0
i: 1
i: 2
i: 3
```
