Struct CommandID 

pub struct CommandID {
    pub command_id_to_uuid: HashMap<u16, String>,
    pub uuid_to_commander: HashMap<String, String>,
    pub command_ids: BTreeSet<u16>,
}

A structure to manage command IDs and their associated UUIDs. Command IDs are allocated from a pool of 0-255. When a command is finished, its ID is returned to the pool.

Fields

command_id_to_uuid: HashMap<u16, String>

A HashMap mapping command IDs to UUID strings.

uuid_to_commander: HashMap<String, String>

A HashMap mapping UUID strings to commander names.

command_ids: BTreeSet<u16>

A BTreeSet of available command IDs.

Implementations

impl CommandID

pub fn new() -> Self

Creates a new CommandID manager with all command IDs available.

pub fn register_command(&mut self, uuid: &str, commander: &str, command_id: u16)

Registers a command with a given UUID, commander name, and command ID.

pub fn get_command_id(&mut self) -> u16

Retrieves and removes an available command ID from the pool.

pub fn finish_command(&mut self, command_id: u16) -> Option<String>

Finishes a command by its ID, removing its associations and returning the UUID. The command ID is returned to the pool of available IDs.

pub fn get_uuid(&self, command_id: u16) -> Option<&String>

Retrieves the UUID associated with a given command ID, if it exists.

pub fn is_command_id_in_use(&self, command_id: u16) -> bool

Checks if a command ID is currently in use.

pub fn get_commander(&self, uuid: &str) -> Option<&String>

Retrieves the commander name associated with a given UUID, if it exists.

Trait Implementations

impl Default for CommandID

fn default() -> Self

Returns the “default value” for a type.
