Implementations§

Source§

impl AttributeUtil

Source

pub fn alter_current_attributes( create: bool, all: &HashMap<CheetahString, Arc<dyn Attribute>>, current_attributes: &HashMap<CheetahString, CheetahString>, new_attributes: &HashMap<CheetahString, CheetahString>, ) -> Result<HashMap<CheetahString, CheetahString>, AttributeError>

Alter the current attributes based on new attribute requests

§Arguments
  • create - If true, we’re creating new attributes, otherwise updating existing ones
  • all - Map of all supported attributes
  • current_attributes - Current attribute values
  • new_attributes - New attribute operations (prefixed with + or -)
§Returns

A Result containing the final attribute map or an error
