Constant R6_GENERATOR_BINDINGS 

const R6_GENERATOR_BINDINGS: &[&str];

The bindings of an R6::R6Class() generator object (R6 2.6). The R6 generator assigns static methods onto that object (Class$name <- function), so a static method under one of these names silently replaces R6’s own: new stops creating objects, set and lock are the generated $set() / $lock() calls, and $new() reads the data fields.
