Parsed #[miniextendr(...)] attributes for a single trait method.

Extracted from method-level attributes to control C wrapper behavior, threading, and R wrapper generation.

Fields

worker: bool

Dispatch to worker thread. Set by explicit #[miniextendr(worker)] or default-worker feature.

unsafe_main_thread: bool

Force execution on R’s main thread (overrides default worker thread for static methods).

coerce: bool

Enable Rf_coerceVector for all parameters.

check_interrupt: bool

Call R_CheckUserInterrupt before the method body.

rng: bool

Wrap the call in GetRNGstate/PutRNGstate for reproducible random number generation.

unwrap_in_r: bool

Return Result<T, E> to R without unwrapping (R wrapper receives the result variant).

skip: bool

Exclude this method from all generated wrappers (C, R, vtable shims).

defaults: HashMap<String, String>

Parameter default values: keys are parameter names, values are R expressions.

r_name: Option<String>

Override the R-facing method name.

strict: bool

Strict output conversion: panic instead of lossy widening for i64/u64/isize/usize.

lifecycle: Option<LifecycleSpec>

Lifecycle specification for deprecation/experimental status.

r_entry: Option<String>

R code to inject at the very top of the wrapper body.

r_post_checks: Option<String>

R code to inject after all checks, immediately before .Call().

r_on_exit: Option<ROnExit>

Register on.exit() cleanup code in the R wrapper.

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.
