Required Methods§

source

fn expand_proc_attr_macros(&self) -> bool

source

fn set_expand_proc_attr_macros(&mut self, value__: bool)

Set the value of the expand_proc_attr_macros input.

See expand_proc_attr_macros for details.

Note: Setting values will trigger cancellation of any ongoing queries; this method blocks until those queries have been cancelled.

source

fn set_expand_proc_attr_macros_with_durability( &mut self, value: bool, durability: Durability )

Set the value of the expand_proc_attr_macros input with a specific durability instead of the default of Durability::LOW. You can use Durability::MAX to promise that its value will never change again.

See expand_proc_attr_macros for details.

Note: Setting values will trigger cancellation of any ongoing queries; this method blocks until those queries have been cancelled.
