Implementations§
source§impl QRng
impl QRng
sourcepub fn new(t: &QRngType, d: u32) -> Option<QRng>
pub fn new(t: &QRngType, d: u32) -> Option<QRng>
This function returns a pointer to a newly-created instance of a quasi-random sequence generator of type T and dimension d. If there is insufficient memory to create the generator then the function returns a null pointer and the error handler is invoked with an error code of ::NoMem.
sourcepub fn init(&mut self)
pub fn init(&mut self)
This function reinitializes the generator self to its starting point. Note that quasi-random sequences do not use a seed and always produce the same set of values.
sourcepub fn get(&self, x: &mut [f64]) -> Value
pub fn get(&self, x: &mut [f64]) -> Value
This function stores the next point from the sequence generator self in the array x. The space available for x must match the dimension of the generator. The point x will lie in the range 0 < x_i < 1 for each x_i.
sourcepub fn name(&self) -> Option<String>
pub fn name(&self) -> Option<String>
This function returns a pointer to the name of the generator.
sourcepub fn size(&self) -> usize
pub fn size(&self) -> usize
These functions return a pointer to the state of generator r and its size.
