Struct Tab 

pub struct Tab {
    pub editor: CodeEditor,
    pub path: Option<PathBuf>,
    pub dirty: bool,
    pub preview: bool,
    pub image: Option<ImageProtocol>,
    pub read_only: bool,
    pub fs_access: FsAccess,
}

One open buffer shown as one tab.

Fields

editor: CodeEditor

The underlying code-editor widget/state.

path: Option<PathBuf>

File path backing this buffer, or None for an untitled buffer.

dirty: bool

Set when the buffer has unsaved edits.

preview: bool

Ephemeral preview tab (single-click / arrow-scan from the explorer).

image: Option<ImageProtocol>

When set, this tab shows an image instead of the text editor.

read_only: bool

When set, the buffer is locked against edits (view-only).

fs_access: FsAccess

When set, the file on disk isn’t writable by this user (T572). Separate from read_only: edits stay allowed (so Save As works) and toggling View-only never clears it.

Implementations

impl Tab

pub fn is_image(&self) -> bool

Whether this tab displays an image rather than editable text.

pub fn text(&self) -> String

Whole buffer text.

pub fn lines(&self) -> Vec<String>

Buffer split into lines (no trailing empty element).

pub fn title(&self) -> String

Title shown on the tab and in the buffer switcher.

pub fn display_path(&self) -> String

Full path for display (status bar / buffer switcher), or "untitled".

pub fn cursor_1based(&self) -> (usize, usize)

1-based (line, column) of the cursor.

pub fn line_count(&self) -> usize

Total line count of this buffer (for the scrollbar).
