struct NormalConfigStruct {
pub:
	mu    f64 = 0.0
	sigma f64 = 1.0
}

Configuration struct for generating normally distributed floats. The default value for mu is 0 and the default value for sigma is 1.

struct PRNGConfigStruct {
pub:
	seed_ []u32
}

PRNGConfigStruct configures a new instance of the default RNG. An omitted or empty seed uses the current time. A nonempty seed must contain two u32s. Explicit seed storage remains owned by the caller; new_default only reads its values.

struct ShuffleConfigStruct {
pub:
	start int
	end   int
}

Configuration struct for the shuffle functions. The start index is inclusive and the end index is exclusive. Set the end to 0 to shuffle until the end of the array.

fn (config ShuffleConfigStruct) validate_for[T](a []T) !

validate_for is a helper function for validating the configuration struct for the given array.
