Function lower_functions_with_metadata 

pub fn lower_functions_with_metadata<I, Ty, V, Info, C>(
    functions: Vec<ParsedFunction<I, Ty>>,
    metadata: &ProgramMetadata<V, Ty, Info>,
    context: &mut C,
) -> Result<Vec<I::Runtime>>
where
    Ty: PartialEq,
    I: Lower<C>,
    C: FunctionScope,

Validate supplied metadata and lower function bodies without consuming it.

Available with program-image-execution. The caller prepares the metadata and context independently, for example by processing individual header declarations. The context may borrow prepared configuration or the metadata itself; neither is moved or cloned by this function.

Function declarations and table bounds are validated before lowering starts. lower_functions prepares label scopes and preserves instruction error context. The returned code can be assembled with ProgramMetadata::into_module, which also checks standard value references.

Errors

Returns declaration, table, or instruction-lowering errors. No partial code is returned; earlier context mutations are not rolled back.
