Module sip128

An implementation of SipHash with a 128-bit output.

Macros

• compress 🔒
• load_int_le 🔒
  Loads an integer of the desired type from a byte stream, in LE order. Uses copy_nonoverlapping to let the compiler generate the most efficient way to load it from a possibly unaligned address.

Structs

• Hash128
  A 128-bit (2x64) hash output
• Hasher 🔒
• Sip13Rounds 🔒
• Sip24Rounds 🔒
• SipHasher
  An implementation of SipHash128 2-4.
• SipHasher13
  An implementation of SipHash128 1-3.
• SipHasher24
  An implementation of SipHash128 2-4.
• State 🔒

Traits

• Hasher128

Functions

• u8to64_le 🔒 ^⚠
  Loads a u64 using up to 7 bytes of a byte slice. It looks clumsy but the copy_nonoverlapping calls that occur (via load_int_le!) all have fixed sizes and avoid calling memcpy, which is good for speed.
