Consumes the stream until the end, ignoring all the data, returning the number of bytes discarded.

Prototype

pub fn discardRemaining(r: *Reader) ShortError!usize

Parameters

See the Reader implementation for detailed diagnostics.

Example

 test discardRemaining {
    var r: Reader = .fixed("foobar");
    r.toss(1);
    try testing.expectEqual(5, try r.discardRemaining());
    try testing.expectEqual(0, try r.discardRemaining());
}

Source

  pub fn discardRemaining(r: *Reader) ShortError!usize {
    var offset: usize = r.end - r.seek;
    r.seek = r.end;
    while (true) {
        offset += r.vtable.discard(r, .unlimited) catch |err| switch (err) {
            error.EndOfStream => return offset,
            else => |e| return e,
        };
    }
}
