hash

Implements the Hashable trait and hash() built-in function.

There are a few main tools in this module:

  • Hashable trait for types implementing __hash__(self, mut hasher)
  • hash[T: Hashable](hashable: T) -> UInt64 built-in function.
  • hash_bytes(bytes: ImmSpan[Byte]) -> UInt64 for arbitrary byte strings, is the workhorse function, which implements efficient hashing via SIMD vectors. See the documentation of this function for more details on the hash implementation.
  • hash(SIMD) and hash(UInt8) implementations These are useful helpers to specialize for the general bytes implementation.

Traits​

  • ​Hashable: A trait for types which specify a function to hash their data.

Functions​

  • ​hash: Hash a Hashable type using its underlying hash implementation.
  • ​hash_bytes: Hash a sequence of bytes using the specified hasher.
