Struct BoxCharacterFilter 

pub struct BoxCharacterFilter(/* private fields */);

A struct that holds a boxed CharacterFilter trait object.

BoxCharacterFilter wraps a Box<dyn CharacterFilter + 'static + Send + Sync>, allowing for dynamic dispatch of character filters while ensuring they are thread-safe and have a 'static lifetime.

Fields

• 0: Box<dyn CharacterFilter + 'static + Send + Sync>:
  • The boxed character filter trait object, which can be any type that implements the CharacterFilter trait. This allows for runtime polymorphism, meaning different character filter implementations can be stored in the same collection or passed around generically.

Trait Bounds

• CharacterFilter: The wrapped object must implement the CharacterFilter trait, which defines the interface for applying filters to text.
• 'static: The wrapped object must have a 'static lifetime, meaning it can live for the duration of the program and does not borrow from temporary data.
• Send and Sync: These bounds ensure the filter can be shared between threads and sent across thread boundaries, making it safe for concurrent use.

Example Usage

BoxCharacterFilter allows you to store and use different types of character filters dynamically, making it easier to apply multiple filters without needing to know their concrete types at compile time.

Trait Implementations

impl Deref for BoxCharacterFilter

type Target = dyn CharacterFilter

The resulting type after dereferencing.

fn deref(&self) -> &dyn CharacterFilter

Dereferences the value.

impl<T: CharacterFilter> From<T> for BoxCharacterFilter

fn from(character_filter: T) -> BoxCharacterFilter

Converts to this type from the input type.
