Function indexOfIgnoreCasePosLinear [src]

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

Prototype

pub fn indexOfIgnoreCasePosLinear(haystack: []const u8, start_index: usize, needle: []const u8) ?usize

Parameters

haystack: []const u8start_index: usizeneedle: []const u8

Source

  pub fn indexOfIgnoreCasePosLinear(haystack: []const u8, start_index: usize, needle: []const u8) ?usize {
    var i: usize = start_index;
    const end = haystack.len - needle.len;
    while (i <= end) : (i += 1) {
        if (eqlIgnoreCase(haystack[i .. i + needle.len], needle)) return i;
    }
    return null;
}
