Struct ProgramImport 

pub struct ProgramImport<'a> {
    pub program: &'a SemanticProgram,
    pub bindings: Option<&'a ProgramBindings>,
    pub roots: &'a [ProgramValue],
    pub input_map: &'a [(ProgramValue, ProgramValue)],
}

Read-only request to import the dependency closure of ordered roots.

Fields

program: &'a SemanticProgram

Immutable source semantic program.

bindings: Option<&'a ProgramBindings>

Tensor bindings frozen with the source program, when structure and bindings should travel together.

A structural import passes None so symbolic extents stay symbolic; a caller that wants the frozen defaults re-attaches them afterwards.

roots: &'a [ProgramValue]

Ordered source roots to remap; empty and duplicate roots are valid.

input_map: &'a [(ProgramValue, ProgramValue)]

Source inputs that already exist in the destination.

A mapped source input reuses the destination value (and its metadata) instead of creating a fresh input, which is how a derivative program lands back on the leaves it was differentiated from.
