Struct DeviceSection 

pub struct DeviceSection<T: DeviceValue, B: AcceleratorBackend> {
    pub atlas_version: u64,
    pub topology_version: u64,
    pub offsets: B::Buffer<u32>,
    pub lengths: B::Buffer<u32>,
    pub values: B::Buffer<T>,
    pub point_count: usize,
    pub value_count: usize,
}

A section layout and its values resident in backend-owned memory.

Fields

atlas_version: u64

Source atlas structural version.

topology_version: u64

Source mesh topology version supplied by the caller.

offsets: B::Buffer<u32>

Per-point offsets in atlas iteration order.

lengths: B::Buffer<u32>

Per-point lengths in atlas iteration order.

values: B::Buffer<T>

Flat field values.

point_count: usize

Number of atlas points.

value_count: usize

Number of scalar values.

Implementations

impl<T: DeviceValue, B: AcceleratorBackend> DeviceSection<T, B>

pub fn upload_from<S: Storage<T>>( backend: &B, section: &Section<T, S>, topology_version: u64, ) -> Result<Self, AcceleratorError>

Upload atlas metadata and values from a host-accessible section.

pub fn refresh_values_from<S: Storage<T>>( &mut self, backend: &B, section: &Section<T, S>, topology_version: u64, ) -> Result<(), AcceleratorError>

Refresh values without rebuilding layout metadata.

pub fn download_into<S: Storage<T> + Clone>( &self, backend: &B, section: &mut Section<T, S>, topology_version: u64, ) -> Result<(), AcceleratorError>

where T: Clone + Default,

Download values into a section with the same atlas layout.

pub fn validate( &self, atlas_version: u64, topology_version: u64, ) -> Result<(), AcceleratorError>

Validate both structural epochs used to construct this section.
