Collection of helpers.
Implementations
impl<'reg> HelperRegistry<'reg>
[src]
pub fn new() -> Self
[src]
Create a collection of helpers.
Helpers configured using the compiler feature flags are automatically added to this collection.
If you need a helper collection without the builtin helpers
use Default::default()
.
pub fn insert(&mut self, name: &'reg str, helper: Box<dyn Helper + 'reg>)
[src]
Insert a helper into this collection.
pub fn remove(&mut self, name: &'reg str)
[src]
Remove a helper from this collection.
pub fn get(&self, name: &str) -> Option<&Box<dyn Helper + 'reg>>
[src]
Get a helper from this collection.
