Struct RenderCtx 

pub struct RenderCtx<'a, 'f> {
    pub focus: FocusTarget,
    pub time: Instant,
    /* private fields */
}

Two lifetimes are required: 'a is the outer &mut Frame borrow passed into RenderCtx::new, and 'f is the frame’s own buffer lifetime. ratatui 0.30’s Terminal::draw callback produces a &mut Frame<'_> whose buffer outlives the local borrow, so collapsing both into one lifetime does not compile. Downstream code that just uses &RenderCtx elides the lifetimes to RenderCtx<'_, '_>.

Fields

focus: FocusTarget

time: Instant

Implementations

impl<'a, 'f> RenderCtx<'a, 'f>

pub fn new( frame: &'a mut Frame<'f>, theme: &'a Theme, caps: &'a TerminalCaps, ) -> RenderCtx<'a, 'f>

pub fn theme(&self) -> &Theme

pub fn caps(&self) -> &TerminalCaps

pub fn buffer_mut(&mut self) -> &mut Buffer

pub fn area(&self) -> Rect

pub fn set_cursor(&mut self, pos: Position)

pub fn hide_cursor(&mut self)

pub fn emit_link(&mut self, range: CellRange, target: LinkTarget)

pub fn with_frame<R>(&mut self, f: impl FnOnce(&mut Frame<'f>) -> R) -> R

Access the underlying Frame for legacy bridging.

Used by LegacyOverlayAdapter to forward Renderable::render calls to legacy Overlay implementations that operate on a raw &mut Frame. NOTE: This is a temporary bridge API. Once all overlays are migrated to Renderable, this accessor should be removed.
