Module extendr_api::wrapper::externalptr
source · Expand description
ExternalPtr is a way to leak Rust allocated data to R, forego deallocation
to R and its GC strategy.
An ExternalPtr encompasses three values, an owned pointer to the Rust
type, a tag and a prot. Tag is a helpful naming of the type, but
it doesn’t offer any solid type-checking capability. And prot is meant
to be R values, that are supposed to be kept together with the ExternalPtr.
Neither tag nor prot are attributes, therefore to use ExternalPtr as
a class in R, you must decorate it with a class-attribute manually.
