Enum Driver 

pub enum Driver {
    Memory,
    File,
    Redis,
}

Which backend to build, and what it needs.

Variants

Memory

Process-local. Fast, and lost on restart — and not shared between workers, which matters for rate limiting.

File

One file per key under CacheConfig::path.

Redis

A Redis server reached over RESP.

Implementations

impl Driver

pub fn parse(name: &str) -> Result<Driver>

Parse a driver name, listing the alternatives when it is not one.

A typo in .env is one of the most common ways to lose an afternoon, so this refuses rather than silently falling back to memory.

pub fn name(&self) -> &'static str
