Overview ¶
Package fastrand exposes an object Rand which can be used as a simple drop-in replacement for `[math/rand.Rand]` where performance or thread safety is required.

Types ¶
type Rand ¶
type Rand struct{}
Rand is an object that behaves largely as-if it was a math/rand.Rand, with the key distinction that it is thread-safe and highly performant.
Under the hood this uses a thread-safe pool of math/rand.Rand objects which it will dynamically create and access for each call. As a result, this does not support setting the seed, since the underlying objects are ephemeral.
func (Rand) ExpFloat64 ¶
ExpFloat64 implements math/rand.Rand.ExpFloat64.
func (Rand) NormFloat64 ¶
NormFloat64 implements math/rand.Rand.NormFloat64.
func (Rand) Read ¶
Read implements math/rand.Rand.Read.
func (Rand) Shuffle ¶
Shuffle math/rand.Rand.Shuffle.
