Enum GuardMode 

pub enum GuardMode {
    CatchUnwind,
    RUnwind,
}

FFI guard mode controlling how panics are caught at Rust-R boundaries.

Variants

CatchUnwind

catch_unwind only. On panic: fire telemetry, then Rf_error (diverges).

Use when R longjmps cannot occur (the closure does not call R APIs).

RUnwind

R_UnwindProtect. Catches both Rust panics and R longjmps.

Use when the closure may call R APIs that can error.

Trait Implementations

impl Clone for GuardMode

fn clone(&self) -> GuardMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GuardMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for GuardMode

fn eq(&self, other: &GuardMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
