Summary

Provides a low-level interface to the hash/crc64 package.

Package crc64 implements the 64-bit cyclic redundancy check, or CRC-64,
checksum. See https://en.wikipedia.org/wiki/Cyclic_redundancy_check for
information.

Constants

Constants are variables with :const true in their metadata. Joker currently does not recognize them as special; as such, it allows redefining them or their values.

• ECMA

  Number v1.0

  The ECMA polynomial, defined in ECMA 182.
  

• ISO

  Number v1.0

  The ISO polynomial, defined in ISO 3309 and used in HDLC.
  

• Size

  Int v1.0

  The size of a CRC-64 checksum in bytes.
  

Variables

(None.)

Functions, Macros, and Special Forms

• Checksum

  Function v1.0

  (Checksum data tab)
  

  Checksum returns the CRC-64 checksum of data
  using the polynomial represented by the Table.
  
  Go input arguments: (data []byte, tab *Table)
  
  Go returns: uint64
  
  Joker input arguments: [^arrayOfByte data, ^*Table tab]
  
  Joker returns: ^Number

• MakeTable

  Function v1.0

  (MakeTable poly)
  

  MakeTable returns a Table constructed from the specified polynomial.
  The contents of this Table must not be modified.
  
  Go input arguments: (poly uint64)
  
  Go returns: *Table
  
  Joker input arguments: [^Number poly]
  
  Joker returns: ^*Table

• New

  Function v1.0

  (New tab)
  

  New creates a new hash.Hash64 computing the CRC-64 checksum using the
  polynomial represented by the Table. Its Sum method will lay the
  value out in big-endian byte order. The returned Hash64 also
  implements encoding.BinaryMarshaler and encoding.BinaryUnmarshaler to
  marshal and unmarshal the internal state of the hash.
  
  Go input arguments: (tab *Table)
  
  Go returns: hash.Hash64
  
  Joker input arguments: [^*Table tab]
  
  Joker returns: ^go.std.hash/Hash64

• Update

  Function v1.0

  (Update crc tab p)
  

  Update returns the result of adding the bytes in p to the crc.
  
  Go input arguments: (crc uint64, tab *Table, p []byte)
  
  Go returns: uint64
  
  Joker input arguments: [^Number crc, ^*Table tab, ^arrayOfByte p]
  
  Joker returns: ^Number

Types
