lz4Compress()

template<typename BufferFactory >

std::size_t ripple::compression_algorithms::lz4Compress	(	void const *	in,

		BufferFactory &&	bf
	)

LZ4 block compression.

Template Parameters

BufferFactory

Callable object or lambda. Takes the requested buffer size and returns allocated buffer pointer.

Parameters

in	Data to compress
inSize	Size of the data
bf	Compressed buffer allocator

Returns

Size of compressed data, or zero if failed to compress
