flexihash-rs

https://github.com/pda/flexihash 的Rust端口，旨在实现1:1兼容性

使用示例

use flexihash::Flexihash;

let fh = Flexihash::new();

// bulk add
fh.add_targets(vec!["cache-1", "cache-2", "cache-3"]);

// simple lookup
fh.lookup("object-a");  // "cache-1"
fh.lookup("object-b");  // "cache-2"

// add and remove
fh.add_target("cache-4");
fh.remove_target("cache-1");

// lookup with next-best fallback (for redundant writes)
fh.lookup_list("object", 2)  // ["cache-2", "cache-4"]

// remove cache-2, expect object to hash to cache-4
fh.remove_target("cache-2")
fh.lookup("object")  // "cache-4"
