pub struct TagManager {
    pub cache: RwLock<HashMap<String, TagMetadata>>,
    pub udt_definitions: RwLock<HashMap<String, UdtDefinition>>,
    /* private fields */
}

Implementations

impl TagManager

pub fn new() -> Self

pub async fn get_metadata(&self, tag_name: &str) -> Option<TagMetadata>

pub async fn update_metadata(&self, tag_name: String, metadata: TagMetadata)

pub async fn validate_tag( &self, tag_name: &str, required_permissions: &TagPermissions, ) -> Result<()>

pub async fn clear_cache(&self)

pub async fn remove_stale_entries(&self)

pub async fn discover_tags(&self, client: &mut EipClient) -> Result<()>

pub async fn discover_udt_members( &self, client: &mut EipClient, udt_name: &str, ) -> Result<Vec<(String, TagMetadata)>>

Discovers members of a UDT/structure

pub fn build_udt_definition_request(&self, udt_name: &str) -> Result<Vec<u8>>

Builds a CIP request to get UDT definition

pub fn parse_udt_definition_response( &self, response: &[u8], udt_name: &str, ) -> Result<UdtDefinition>
