ClassNameEntry

miniextendr_api::registry

Struct ClassNameEntry

pub struct ClassNameEntry {
    pub rust_type: &'static str,
    pub r_class_name: &'static str,
    pub class_system: &'static str,
}

Expand description

Entry mapping a Rust type name to its R-visible class name and class system.

Emitted by every #[miniextendr(env|r6|s3|s4|s7|vctrs)] impl block. Used by the resolver in write_r_wrappers_to_file to replace .__MX_CLASS_REF_<RustName>__ placeholders with the actual R class name.

Fields§

§rust_type: &'static str

Rust type identifier, e.g. "S7Shape".

§r_class_name: &'static str

R-visible class name. Equals rust_type unless class = "Override" was set on the impl block, in which case it is the override string.

§class_system: &'static str

Class system tag: "env" | "r6" | "s3" | "s4" | "s7" | "vctrs".

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
