Function iota_json::primitive_type

pub fn primitive_type(
    view: &CompiledModule,
    type_args: &[TypeTag],
    param: &SignatureToken,
) -> (bool, Option<MoveTypeLayout>)

Checks if a give SignatureToken represents a primitive type and, if so, returns MoveTypeLayout for this type (if available). The reason we need to return both information about whether a SignatureToken represents a primitive and an Option representing MoveTypeLayout is that there can be signature tokens that represent primitives but that do not have corresponding MoveTypeLayout (e.g., SignatureToken::DatatypeInstantiation).
