Function LimitedInputStream.peek
Returns a temporary reference to the data that is currently buffered.
const(ubyte)[] peek() @safe;
The returned slice typically has the size leastSize()
or 0
if dataAvailableForRead()
returns false
. Streams that don't have an internal buffer will always return an empty
slice.
Note that any method invocation on the same stream potentially invalidates the contents of the returned buffer.
