Struct SidecarSlot 

pub(crate) struct SidecarSlot {
    pub(crate) name: Ident,
    pub(crate) r_name: String,
    ty: Type,
    vis: Visibility,
    is_public: bool,
    pub(crate) kind: SlotKind,
    access: SidecarAccess,
    prop_doc: Option<String>,
    setter_invisible: Option<bool>,
}

Information about a single #[r_data]-annotated sidecar slot field.

Collected during struct field parsing and used to generate FFI getter/setter functions and R wrapper code for each public slot.

Fields

name: Ident

Rust identifier of the field (e.g., count, name). The C symbols, the R_CallMethodDef statics and the Rust accessors are named by it.

r_name: String

The field’s R name: #[r_data(name = "...")], else the Rust identifier (#1891). Every R-facing string uses it: .rdata_fields_T, the $ switch labels, the R6 binding / S7 property, the standalone T_get_<name>() / T_set_<name>() and the setter’s message. A Sidecar field’s save slot is named by it too (SIDECAR_NAMES, the name the accessors and __mx_visit_sidecars pass, #2215).

ty: Type

Rust type of the field, used in conversion-based getter/setter codegen.

vis: Visibility

The field’s visibility, which its generated Rust accessors take.

is_public: bool

Whether the field is pub. Only public fields get R accessor functions.

kind: SlotKind

Determines the codegen strategy for reading/writing this slot.

access: SidecarAccess

The Rust accessors of a Sidecar<T> field (#[r_data(ref | mut)]); unused by the other kinds.

prop_doc: Option<String>

Optional documentation string for the S7 @prop tag. Sourced from #[r_data(prop_doc = "...")]. None means no doc was supplied; a default fallback string is used at emit time.

setter_invisible: Option<bool>

Explicit setter visibility; each generated setter keeps its default when absent.

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.
