Struct BlockSize

pub struct BlockSize {
    pub x: u32,
    pub y: u32,
    pub z: u32,
}

Dimensions of a thread block, or the number of threads in a block.

Each component of a BlockSize must be at least 1. The maximum size depends on your device’s compute capability, but maximums of x = 1024, y = 1024, z = 64 are common. In addition, the limit on total number of threads in a block (x * y * z) is also defined by the compute capability, typically 1024. Launching a kernel with a block size greater than these limits will cause an error.

Fields

x: u32

X dimension of each thread block

y: u32

Y dimension of each thread block

z: u32

Z dimension of each thread block

Implementations

impl BlockSize

pub fn x(x: u32) -> BlockSize

Create a one-dimensional block of x threads

pub fn xy(x: u32, y: u32) -> BlockSize

Create a two-dimensional block of x * y threads

pub fn xyz(x: u32, y: u32, z: u32) -> BlockSize

Create a three-dimensional block of x * y * z threads

Trait Implementations

impl Clone for BlockSize

fn clone(&self) -> BlockSize

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockSize

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> From<&'a BlockSize> for BlockSize

fn from(other: &BlockSize) -> BlockSize

Converts to this type from the input type.

impl From<(u32, u32)> for BlockSize

fn from((x, y): (u32, u32)) -> BlockSize

Converts to this type from the input type.

impl From<(u32, u32, u32)> for BlockSize

fn from((x, y, z): (u32, u32, u32)) -> BlockSize

Converts to this type from the input type.

impl From<u32> for BlockSize

fn from(x: u32) -> BlockSize

impl PartialEq for BlockSize

fn eq(&self, other: &BlockSize) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
