Struct vulkano::image::SubresourceLayout

pub struct SubresourceLayout {
    pub offset: DeviceSize,
    pub size: DeviceSize,
    pub row_pitch: DeviceSize,
    pub array_pitch: Option<DeviceSize>,
    pub depth_pitch: Option<DeviceSize>,
}

Describes the memory layout of a single subresource of an image.

The address of a texel at (x, y, z, layer) is layer * array_pitch + z * depth_pitch + y * row_pitch + x * size_of_each_texel + offset. size_of_each_texel must be determined depending on the format. The same formula applies for compressed formats, except that the coordinates must be in number of blocks.

Fields

offset: DeviceSize

The number of bytes from the start of the memory to the start of the queried subresource.

size: DeviceSize

The total number of bytes for the queried subresource.

row_pitch: DeviceSize

The number of bytes between two texels or two blocks in adjacent rows.

array_pitch: Option<DeviceSize>

For images with more than one array layer, the number of bytes between two texels or two blocks in adjacent array layers.

depth_pitch: Option<DeviceSize>

For 3D images, the number of bytes between two texels or two blocks in adjacent depth layers.

Trait Implementations

impl Clone for SubresourceLayout

fn clone(&self) -> SubresourceLayout

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SubresourceLayout

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

Formats the value using the given formatter.

impl PartialEq for SubresourceLayout

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

This method tests for self and other values to be equal, and is used by ==.

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

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