Struct RenderSession 

pub struct RenderSession { /* private fields */ }

Opaque, backend-backed iterative render session.

Implementations

impl RenderSession

pub fn with_warnings(self, warnings: Vec<Diagnostic>) -> Self

Attach session-level warnings. Appended to RenderResult::warnings on every RenderSession::render call and surfaced verbatim by RenderSession::warnings.

pub fn page_count(&self) -> usize

pub fn warnings(&self) -> &[Diagnostic]

Snapshot of session-level warnings attached at Backend::open time.

Empty when the backend produced none. These are also appended to RenderResult::warnings on each RenderSession::render call; this accessor surfaces them to consumers (e.g. canvas previews) that don’t go through render().

pub fn render(&self, opts: &RenderOptions) -> Result<RenderResult, RenderError>
