Struct WeightComponentPayload 

pub struct WeightComponentPayload<'source> { /* private fields */ }

Validated physical bytes for one model weight component.

Borrowed bytes allow mmap-backed dense weights to avoid a host copy. Owned bytes cover format adapters that must repack before device upload.

Implementations

impl<'source> WeightComponentPayload<'source>

pub fn new( component: &WeightComponentSpec, external_name: impl Into<String>, source_file: impl Into<String>, dimensions: Vec<u64>, element_type: ElementType, bytes: impl Into<Cow<'source, [u8]>>, ) -> Result<Self, VNextError>

pub fn from_ordered_sources( component: &WeightComponentSpec, external_names: Vec<String>, source_files: Vec<String>, dimensions: Vec<u64>, element_type: ElementType, bytes: impl Into<Cow<'source, [u8]>>, ) -> Result<Self, VNextError>

Construct a payload materialized from multiple ordered checkpoint tensors. Multi-source order is part of the component schema, so packed projections cannot silently swap their logical partitions.

pub fn with_retained_host_memory( self, retained_host_memory: RetainedHostMemoryRegion, ) -> Result<Self, VNextError>

Attach the stable owner for an otherwise borrowed payload. Pointer and length identity are checked here so a backend cannot accidentally retain a different mmap range than the bytes validated against the schema.
