Enum LibraryLinkFunction 

pub enum LibraryLinkFunction {
    Native {
        name: &'static str,
        signature: fn() -> Result<(Vec<Expr>, Expr), String>,
    },
    Wstp {
        name: &'static str,
    },
    Wxf {
        name: &'static str,
        signature: fn() -> Result<(Vec<Expr>, Expr), String>,
    },
}

LibraryLinkFunction is a type alias for ExportEntry. Lives at this path because the proc-macro emits macro_utils::LibraryLinkFunction::{Native,Wstp,Wxf}{...} for inventory submission. Inventory entry for one #[export]-marked function.

Replaces the legacy LibraryLinkFunction enum from wolfram-library-link. All three export-mode runtimes (wolfram-export-native, wolfram-export-wstp, wolfram-export-wxf) submit entries of this single shared type to one global inventory; exported_library_functions_association iterates that inventory regardless of mode.

Variants

Native

Native MArgument-based export.

Fields

name: &'static str

Exported symbol name (matches the #[no_mangle] extern "C" symbol).

signature: fn() -> Result<(Vec<Expr>, Expr), String>

Closure returning (arg types, return type) as Wolfram Language Exprs.

See the implementation note on LibraryLinkFunction::Native::signature for why this is a fn pointer rather than a Box<dyn ...>.

Wstp

WSTP LinkObject-based export.

Fields

name: &'static str

Exported symbol name.

Wxf

Typed-args WXF-based export (NEW). Wire shape is {ByteArray} -> ByteArray at the LibraryLink level; the byte arrays carry WXF-encoded payloads of the user-declared Rust types.

Fields

name: &'static str

Exported symbol name.

signature: fn() -> Result<(Vec<Expr>, Expr), String>

Closure returning (arg types, return type) as Wolfram Language Exprs — used for the manifest’s typed signature display, not for the WL-side LibraryFunctionLoad call (which is always {ByteArray} -> ByteArray).
