# Module hashes

This module implements efficient computations of hash values for diverse Nimrod types.

# Imports

strutils

# Types

    THash* = int

  a hash value; hash tables using these values should always have a size of a power of two and can use the `and` operator instead of `mod` for truncation of the hash value.

# Procs

    proc `!&`*(h: THash; val: int): THash {.inline.}

  mixes a hash value h with val to produce a new hash value. This is only needed if you need to implement a hash proc for a new datatype.

    proc `!$`*(h: THash): THash {.inline.}

  finishes the computation of the hash value. This is only needed if you need to implement a hash proc for a new datatype.

    proc hashData*(Data: Pointer; Size: int): THash

  hashes an array of bytes of size size

    proc hash*(x: Pointer): THash {.inline.}

  efficient hashing of pointers

    proc hash*[T: proc](x: T): THash {.inline.}

  efficient hashing of proc vars; closures are supported too.

    proc hash*(x: int): THash {.inline.}

  efficient hashing of integers

    proc hash*(x: int64): THash {.inline.}

  efficient hashing of integers

    proc hash*(x: char): THash {.inline.}

  efficient hashing of characters

    proc hash*(x: string): THash

  efficient hashing of strings

    proc hashIgnoreStyle*(x: string): THash

  efficient hashing of strings; style is ignored

    proc hashIgnoreCase*(x: string): THash

  efficient hashing of strings; case is ignored

    proc hash*[T: tuple](x: T): THash

  efficient hashing of tuples.

    proc hash*(x: float): THash {.inline.}
