Source 
pub fn add_binding_json(
    root: &Path,
    mem: &str,
    name: &str,
    patch_json: &str,
) -> Result<Binding, PipelineEditError>
Expand description

Create a binding from a JSON BindingPatch applied to the default scaffold. Refuses when (mem, name) already holds a record (PipelineEditError::AlreadyExists), when the patch leaves destination_mem empty (PipelineEditError::InvalidJson), or when the candidate fails in-record validation (PipelineEditError::Capability — every refusal blocks; a fresh record has no pre-existing state to grandfather). Returns the written record.
