Struct EditorSession 

pub struct EditorSession { /* private fields */ }

Multi-buffer editor session with active buffer + MRU ordering.

Implementations

impl EditorSession

pub fn open_initial_file(path: impl AsRef<Path>) -> Result<Self>

Build a new session with a single initial file buffer.

pub fn open_file(&mut self, path: impl AsRef<Path>) -> Result<BufferId>

Open (or switch to) a file-backed buffer.

• Existing open path: activates and returns existing buffer ID.
• Missing path: creates an empty file-backed buffer marked as new.

pub fn open_ui_buffer( &mut self, name: impl Into<String>, initial_text: &str, ) -> BufferId

Open an in-memory UI buffer (future floating picker/menu hook).

pub fn active_id(&self) -> BufferId

pub fn activate(&mut self, id: BufferId) -> bool

Activate the target buffer and promote it to the top of MRU order.

pub fn active_buffer(&self) -> &TextBuffer

pub fn active_buffer_mut(&mut self) -> &mut TextBuffer

pub fn active_meta(&self) -> &BufferMeta

pub fn active_meta_mut(&mut self) -> &mut BufferMeta

pub fn set_active_dirty(&mut self, dirty: bool)

pub fn recompute_active_dirty(&mut self) -> bool

Recompute active buffer dirty state by comparing current contents against the last clean snapshot (opened-from-disk or last successful save).

pub fn mark_active_clean(&mut self)

Record the active buffer’s current contents as the clean snapshot.

pub fn any_dirty(&self) -> bool

pub fn switch_next_mru(&mut self) -> Option<BufferId>

Cycle to the next buffer in MRU order.

pub fn switch_prev_mru(&mut self) -> Option<BufferId>

Cycle to the previous buffer in MRU order.

pub fn summaries(&self) -> Vec<BufferSummary>

pub fn close_buffer(&mut self, id: BufferId) -> bool

Close a buffer by id, activating the next MRU buffer if needed.

Returns false if the id does not exist or this is the last remaining buffer.

pub fn close_active_buffer(&mut self) -> bool

Close the currently active buffer.

pub fn save_active(&mut self) -> Result<()>

Save the active file-backed buffer.

pub fn buffer(&self, id: BufferId) -> Option<&TextBuffer>

pub fn buffer_mut(&mut self, id: BufferId) -> Option<&mut TextBuffer>

pub fn meta(&self, id: BufferId) -> Option<&BufferMeta>
