Implementations

impl ILTagCreatorEngine

pub fn new(strict: bool) -> ILTagCreatorEngine

Creates a new instance of the ILTagCreatorEngine.

Arguments:

• strict: Strict mode. If false, unknown tags will be mapped to RawTag instances.

pub fn strict(&self) -> bool

Returns the current strict flag.

pub fn register(
    &mut self,
    tag_id: u64,
    creator: Box<dyn ILTagCreator>
) -> Option<Box<dyn ILTagCreator>>

Registers a new ILTagCreator.

Arguments:

• tag_id: The tag id;
• creator: The new creator;

Returns:

• Some<Box<dyn ILTagCreator>>: The previously registered creator for the specified id;
• None: If the id is not associated with a new creator;

pub fn deregister(&mut self, tag_id: u64) -> Option<Box<dyn ILTagCreator>>

Deregisters a ILTagCreator.

Arguments:

• tag_id: The tag id;

Returns:

• Some<Box<dyn ILTagCreator>>: The previously registered creator for the specified id;
• None: If the id is not associated with a new creator;

pub fn create_tag(&self, tag_id: u64) -> Option<Box<dyn ILTag>>

Creates a new empty tag for the given id. It uses the registered creators to perform the operation.

Arguments:

• tag_id: The tag id;

Returns:

• Some<Box<dyn ILTag>>: The new empty tag instance;
