shuffle

Shuffle a slice into a random order.

Note that this will not yield consistent results across all targets due to dependence on the representation of usize as an index. See shuffleWithIndex for further commentary.

Function parameters

Parameters

#
T:type
buf:[]T

Fast unbiased random numbers.

Types

Functions

#
bytes
Read random bytes into the specified buffer until full.
enumValue
Returns a random value from an enum, evenly distributed.
enumValueWithIndex
Returns a random value from an enum, evenly distributed.
int
Returns a random int `i` such that `minInt(T) <= i <= maxInt(T)`.
uintLessThanBiased
Constant-time implementation off `uintLessThan`.
uintLessThan
Returns an evenly distributed random unsigned integer `0 <= i < less_than`.
