ConditionCall

miniextendr_api::condition

Enum ConditionCall 

Source 
pub enum ConditionCall {
    Inherit,
    None,
}
Expand description

Whether a condition reports a call (conditionCall()): the per-condition equivalent of R’s warning(..., call. = FALSE) / stop(..., call. = FALSE).

Every condition a #[miniextendr] function raises carries the call its transport captured: the wrapper’s call as written (or the caller’s, under call = caller), NULL in ALTREP and connection callbacks. A condition about the data rather than the call opts out with ConditionCall::None; its siblings from the same function keep their call.

Spellings: call = none first in crate::warning!, crate::error!, crate::condition! and the defer_*! macros; RError::without_call; #[condition(call = none)] on a #[derive(RCondition)] type or variant; or an RConditionData::call impl.

On the tagged condition value the choice is the call slot itself: FALSE for ConditionCall::None, read back by the R helper (and by the trait-ABI re-panic, RCondition::from_tagged_sexp) as “no call”.

Variants§

§

Inherit

The call the transport captured (the default).

§

None

No call: conditionCall() is NULL and the printed condition has no In f(...) : prefix.

Implementations§

Source§

impl ConditionCall

Source

pub fn apply(self, call: Option<SEXP>) -> Option<SEXP>

call when the condition keeps its call, None otherwise: the call to hand a transport that takes the R call object directly.
