rand

type Kind int

type Rand interface {
	// Bytes generates a new random byte slice of the specified size.
	// This method allocates a new slice for each call. For maximum performance when
	// repeatedly generating random bytes into a pre-existing buffer, prefer the Read method.
	Bytes(size int) ([]byte, error)
	// String generates a new random string of the specified size.
	// This method involves internal byte slice allocation and conversion to string.
	// For scenarios requiring extreme performance and byte-level control, consider
	// using RandBytes or Read and managing string conversion manually if profiling
	// indicates this is a bottleneck.
	String(size int) (string, error)
	// Read populates the given byte slice with random bytes from the generator's character set.
	// It implements the io.Reader interface. This is the most performant method for
	// filling pre-allocated buffers, as it avoids internal allocations of the output slice.
	Read(p []byte) (n int, err error)
