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, surfaced by RenderSession::warnings and appended to RenderResult::warnings on every RenderSession::render call.

A Backend chains this onto the session it returns from open to carry non-fatal open-time diagnostics. The built-in Typst backend emits none, so the channel stays empty unless a backend opts in.

pub fn page_count(&self) -> usize

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

Session-level warnings attached at Backend::open time, also appended to RenderResult::warnings on each RenderSession::render call. Exposed for consumers (e.g. canvas previews) that never call render().

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