Attempts to write the given bytes to this stream.
PNG.BytestreamDestination.swift:30mutating func write(_ buffer: [UInt8]) -> Void? Parameters
- bytes
The bytes to write.
Returns
A Void tuple, or nil if the write attempt failed. This method should return nil even if any number of bytes less than bytes.count were successfully written.
A successful call to this function should affect the bytestream state such that subsequent calls should pick up where the last call left off.
The rest of the library interprets a nil return value from this function as indicating a write failure.
