Implementations§

source§

impl<'meta> MetadataListenerLocalBuilder<'meta>

source

pub fn property<F>(self, property: F) -> Self
where F: Fn(u32, Option<&str>, Option<&str>, Option<&str>) -> i32 + 'static,

Add property changed callback.

Callback parameters: subject, key, type, value.

None for value means removal of property. None for key means removal of all properties.
