Enum RDataAccessors 

pub enum RDataAccessors {
    Off,
    GetSet,
    GetOnly,
}

What the impl option r_data_accessors asks for: the class-level form of the pub #[r_data] fields of #[derive(ExternalPtr)], next to the standalone Type_get_f() / Type_set_f() every class gets.

R6 gets active bindings, S7 properties, and S3, S4 and env classes $ / [[ field methods (#1848, field_syntax.rs).

Variants

Off

No option: only the standalone accessors.

GetSet

r_data_accessors: a getter and a setter per field.

GetOnly

r_data_accessors = "get" (S3, S4, env): $ / [[ read the fields and no $<- / [[<- is generated, for a class whose own replacement methods write them (for example copy-on-modify setters that return a new object).

Implementations

impl RDataAccessors

pub fn enabled(self) -> bool

Whether the class wires its fields in at all.

pub fn setters(self) -> bool

Whether the class gets field setters ($<- / [[<-).
