Struct ParentView 

pub struct ParentView { /* private fields */ }

Everything a builder reads of the scope it builds under: the names the parent declares, the modifier on each output, the ledger the child’s compile is charged to, and the cells in scope there — each a live handle rather than a copy.

That is the whole parent surface finalize touches. It was an Arc<ScopeKernel<P>> first, so a caller holding a plain kernel had to clone one into existence to ask; then an Arc<PolydatProgram>, which a compiled kernel does not keep. It is the answers now, so a parent of any engine can give them.

Implementations

impl ParentView

pub fn of_kernel(parent: &dyn Kernel) -> Self

The view a kernel of any engine presents to a subcontext built under it.

pub fn of(parent: &PolydatKernel) -> Self

Self::of_kernel for the interpreter’s kernel type, which most callers hold.

pub fn output_names(&self) -> &[String]

The names the parent declares as outputs.

pub fn input_names(&self) -> &[String]

The names the parent declares as inputs, coordinates included.

pub fn output_modifier(&self, name: &str) -> BindingModifier

The modifier on a named output; NONE for a name the parent does not declare.

pub fn ledger(&self) -> &Arc<CompileLedger>

The ledger the child’s compile is charged to: a subscope is a program of the parent’s tree.

pub fn shared_cells(&self) -> &[SharedCellInScope]

The shared cells visible at the parent, its own and every ancestor’s that reached it.

Trait Implementations

impl Clone for ParentView

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
