lua

Overview ¶

Package lua exposes hex/cache to Lua scripts as the "cache" module.

local cache = require("cache")

local ok, err = cache.set("greeting", "hi")             -- no TTL
local ok, err = cache.set("hot", "value", 60)           -- 60s TTL
local v, hit, err = cache.get("greeting")
local ok = cache.has("greeting")
cache.delete("greeting")
cache.clear()                                            -- driver may refuse
local n, err = cache.increment("counter", 1)

Values are strings on the Lua side; hex/cache stores raw []byte. Structured values should be JSON-encoded before caching — a gopher-json module is on the follow-up list.
