Struct ToolState 

pub struct ToolState {
    pub open_files: HashMap<PathBuf, FileState>,
    pub current_file: Option<PathBuf>,
    pub history: Vec<StateSnapshot>,
    pub working_directory: PathBuf,
    /* private fields */
}

Represents the state of the tool system

Fields

open_files: HashMap<PathBuf, FileState>

Currently open files with their windowed views

current_file: Option<PathBuf>

The currently active file

history: Vec<StateSnapshot>

Session history for undo/redo

working_directory: PathBuf

Current working directory

Implementations

impl ToolState

pub fn new() -> Self

Create a new tool state

pub fn open_file( &mut self, path: PathBuf, content: Vec<String>, window_size: usize, ) -> Result<()>

Open a file and add it to the state

pub fn get_current_file_state(&self) -> Option<&FileState>

Get the current file state

pub fn get_current_file_state_mut(&mut self) -> Option<&mut FileState>

Get mutable current file state

pub fn switch_to_file(&mut self, path: &PathBuf) -> Result<(), ToolError>

Switch to a different open file

pub fn close_file(&mut self, path: &PathBuf)

Close a file

pub fn create_snapshot(&self, operation: String) -> StateSnapshot

Create a snapshot for history

pub fn push_history(&mut self, operation: String)

Add to history

pub fn get_summary(&self) -> String

Get state summary for display

pub fn request_cancel(&self)

Signal cancellation — sets the shared flag so running tools can check it.

pub fn reset_cancel(&self)

Reset the cancel signal (e.g. before starting a new tool call).

pub fn is_cancelled(&self) -> bool

Check whether cancellation has been requested.

pub fn cancel_signal(&self) -> Arc<AtomicBool>

Return a clone of the inner Arc<AtomicBool> so a tool can check the signal without holding the Mutex<ToolState> lock.

Trait Implementations

impl Default for ToolState

fn default() -> Self

Returns the “default value” for a type.
