Struct CompletionData 

pub struct CompletionData { /* private fields */ }

Thread-safe storage for dynamic command and argument completions.

Clone this handle and pass it to background threads that need to update available completions (e.g. when the harness sends a model list or an extension publishes an action schema).

Implementations

impl CompletionData

pub fn new() -> Self

Creates empty, shareable dynamic completion storage.

pub fn set_dynamic_commands(&self, commands: Vec<CommandCompletion>)

Replaces extension-provided root commands shown alongside the static command registry.

pub fn set_dynamic_commands_and_arg_completers( &self, commands: Vec<CommandCompletion>, arg_completers: Vec<(CommandName, ArgCompleter)>, )

Replaces extension-provided root commands and their nested argument/subcommand completers as one atomic snapshot.

pub fn set_static_command_descriptions( &self, descriptions: impl IntoIterator<Item = (CommandName, String)>, )

Replaces descriptions for existing intrinsic command-root candidates.

This changes display text only: it cannot add a command or alter its insertion text.

pub fn set_arg_completions( &self, command: CommandName, items: Vec<CompletionItem>, )

Sets a flat, single-arg completion list for a command. Items are ranked prefix-match-first, substring-match-second (case-insensitive). For commands that take more than one arg or need to react to prior args, use CompletionData::set_arg_completer.

pub fn set_arg_completer(&self, command: CommandName, completer: ArgCompleter)

Registers a custom argument completer for a command. The closure receives the args typed so far (with the partial last element being completed) and returns ranked candidates.

pub fn set_agent_mention_completer(&self, completer: ArgCompleter)

Registers prompt-text completion for active agent mentions typed as @<partial-agent-id>.

pub fn set_session_completer(&self, completer: ArgCompleter)

Registers prompt-text completion for running sessions typed as &<partial-session-id>.

impl Default for CompletionData

fn default() -> Self
