Struct SidecarSlot 

struct SidecarSlot {
    name: Ident,
    ty: Type,
    index: usize,
    is_public: bool,
    kind: SlotKind,
    prop_doc: Option<String>,
}

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).

ty: Type

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

index: usize

Zero-based index of this slot in the protection VECSXP (offset from PROT_BASE_LEN, which reserves slots for type ID and user data).

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.

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.

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.
