pub struct ConfigVars { /* private fields */ }Expand description
Map of configs already bound to a variable.
The map only holds a weak reference to the variables.
Implementations§
source§impl ConfigVars
impl ConfigVars
sourcepub fn get_or_bind<T: ConfigValue>(
&mut self,
key: ConfigKey,
bind: impl FnOnce(&ConfigKey) -> BoxedVar<T>,
) -> BoxedVar<T>
pub fn get_or_bind<T: ConfigValue>( &mut self, key: ConfigKey, bind: impl FnOnce(&ConfigKey) -> BoxedVar<T>, ) -> BoxedVar<T>
Gets the already bound variable or calls bind to generate a new binding.
sourcepub fn get_or_bind_contains(
&mut self,
key: ConfigKey,
bind: impl FnOnce(&ConfigKey) -> BoxedVar<bool>,
) -> BoxedVar<bool>
pub fn get_or_bind_contains( &mut self, key: ConfigKey, bind: impl FnOnce(&ConfigKey) -> BoxedVar<bool>, ) -> BoxedVar<bool>
Bind the contains variable.
sourcepub fn rebind(&mut self, source: &mut dyn AnyConfig)
pub fn rebind(&mut self, source: &mut dyn AnyConfig)
Bind all variables to the new source.
If the map entry is present in the source the variable is updated to the new value, if not the entry
is inserted in the source. The variable is then bound to the source.
sourcepub fn low_memory(&mut self)
pub fn low_memory(&mut self)
System warning low memory, flush caches.
