Struct wasmtime_environ::__core::hash::SipHasher
1.0.0 · source · pub struct SipHasher(_);
👎Deprecated since 1.13.0: use
std::collections::hash_map::DefaultHasher
insteadExpand description
An implementation of SipHash 2-4.
See: https://131002.net/siphash/
SipHash is a general-purpose hashing function: it runs at a good
speed (competitive with Spooky and City) and permits strong keyed
hashing. This lets you key your hash tables from a strong RNG, such as
rand::os::OsRng
.
Although the SipHash algorithm is considered to be generally strong, it is not intended for cryptographic purposes. As such, all cryptographic uses of this implementation are strongly discouraged.
