Trait Implementations

impl BrowserBackend for NativeBackend

fn render<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, diagram_type: &'life1 str, source: &'life2 str, format: &'life3 str, ) -> Pin<Box<dyn Future<Output = DiagramResult<Vec<u8>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Renders a diagram using the browser.

fn health<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Value> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Returns health information about the browser instance/pool.
