Implementations

impl ConditionBuilder

pub fn set_message( self, message: impl IntoIterator<Item = impl Into<String>>, ) -> Self

Set the condition message. Accepts any iterable of strings.

pub fn set_kind(self, kind: ConditionKind) -> Self

Set the condition kind, which determines the base R class hierarchy.

pub fn set_class( self, class: impl IntoIterator<Item = impl Into<String>>, ) -> Self

Set user-defined subclasses. These are prepended to the base classes derived from ConditionKind.

pub fn set_call(self, call: Language) -> Self

Set the call associated with the condition.

pub fn set_parent(self, parent: impl Into<RCondition>) -> Self

Set a parent condition. Accepts anything that converts into RCondition, including a Condition.

pub fn set_trace(self, trace: List) -> Self

Set the traceback. The structure of the list is not validated.

pub fn build(self) -> Condition

Consume the builder and produce a Condition.

Trait Implementations

fn default() -> Self

Returns the “default value” for a type.
