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.

(None.)

Variables

• Reader

  Var v1.0

  Reader is a global, shared instance of a cryptographically
  secure random number generator.
  
  On Linux, FreeBSD, Dragonfly and Solaris, Reader uses getrandom(2) if
  available, /dev/urandom otherwise.
  On OpenBSD and macOS, Reader uses getentropy(2).
  On other Unix-like systems, Reader reads from /dev/urandom.
  On Windows systems, Reader uses the RtlGenRandom API.
  On Wasm, Reader uses the Web Crypto API.
  

Functions, Macros, and Special Forms

• Int

  Function v1.0

  (Int rand max)
  

  Int returns a uniform random value in [0, max). It panics if max <= 0.
  
  Go input arguments: (rand io.Reader, max *math/big.Int)
  
  Go returns: (n *math/big.Int, err error)
  
  Joker input arguments: [^go.std.io/Reader rand, ^go.std.math.big/*Int max]
  
  Joker returns: [^go.std.math.big/*Int n, ^Error err]

• Prime

  Function v1.0

  (Prime rand bits)
  

  Prime returns a number of the given bit length that is prime with high probability.
  Prime will return error for any error returned by rand.Read or if bits < 2.
  
  Go input arguments: (rand io.Reader, bits int)
  
  Go returns: (*math/big.Int, error)
  
  Joker input arguments: [^go.std.io/Reader rand, ^Int bits]
  
  Joker returns: [^go.std.math.big/*Int, ^Error]

• Read

  Function v1.0

  (Read b)
  

  Read is a helper function that calls Reader.Read using io.ReadFull.
  On return, n == len(b) if and only if err == nil.
  
  Go input arguments: (b []byte)
  
  Go returns: (n int, err error)
  
  Joker input arguments: [^arrayOfByte b]
  
  Joker returns: [^Int n, ^Error err]
