Function discardAll [src]

Skips the next n bytes from the stream, advancing the seek position. Unlike toss which is infallible, in this function n can be any amount. Returns error.EndOfStream if fewer than n bytes could be discarded. See also: toss discardRemaining discardShort discard

Prototype

pub fn discardAll(r: *Reader, n: usize) Error!void

Parameters

r: *Readern: usize

Possible Errors

EndOfStream

ReadFailed

See the Reader implementation for detailed diagnostics.

Example

 test discardAll {
    var r: Reader = .fixed("foobar");
    try r.discardAll(3);
    try testing.expectEqualStrings("bar", try r.take(3));
    try r.discardAll(0);
    try testing.expectError(error.EndOfStream, r.discardAll(1));
}

Source

  pub fn discardAll(r: *Reader, n: usize) Error!void {
    if ((try r.discardShort(n)) != n) return error.EndOfStream;
}
