impl CapsRef

pub fn set(&mut self, name: impl IntoGStr, value: impl ToSendValue + Sync)

Sets field name to the given value value.

Overrides any default or previously defined value for name.

pub fn set_if( &mut self, name: impl IntoGStr, value: impl ToSendValue + Sync, predicate: bool, )

This has no effect if iter is empty, i.e. previous value for name is unchanged.
