Zig 0.17.0-dev (Split by item)

This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig library itself.

findPosLinear

Consider using findPos instead of this, which will automatically use a more sophisticated algorithm on larger inputs.

mem.findPosLinear

pub fn findPosLinear(comptime T: type, haystack: []const T, start_index: usize, needle: []const T) ?usize

File

lib/std/mem.zig:1454

Code

pub fn findPosLinear(comptime T: type, haystack: []const T, start_index: usize, needle: []const T) ?usize {
    if (needle.len > haystack.len) return null;
    var i: usize = start_index;
    const end = haystack.len - needle.len;
    while (i <= end) : (i += 1) {
        if (eql(T, haystack[i..][0..needle.len], needle)) return i;
    }
    return null;
}
