http.zlib
An abstraction layer over the various lua zlib libraries.
engine {#http.zlib.engine}
Currently either "lua-zlib" or "lzlib"
inflate() {#http.zlib.inflate}
Returns a closure that inflates (uncompresses) a zlib stream.
The closure takes a string of compressed data and an end of stream flag (boolean) as parameters and returns the inflated output as a string. The function will throw an error if the input is not a valid zlib stream.
deflate() {#http.zlib.deflate}
Returns a closure that deflates (compresses) a zlib stream.
The closure takes a string of uncompressed data and an end of stream flag (boolean) as parameters and returns the deflated output as a string.
Example {#http.zlib-example}
local zlib = require "http.zlib"
local original = "the racecar raced around the racecar track"
local deflater = zlib.deflate()
local compressed = deflater(original, true)
print(#original, #compressed) -- compressed should be smaller
local inflater = zlib.inflate()
local uncompressed = inflater(compressed, true)
assert(original == uncompressed)
