Struct Worker 

pub struct Worker { /* private fields */ }

One child process with bounded messages, cancellation and failure cleanup. Applications own the scheduling queue and decide when to recycle or retire it.

Implementations

impl Worker

pub fn requests_completed(&self) -> usize

pub fn spawn(program: &Path, worker_argument: &str) -> Result<Self>

pub fn render( &mut self, source: &str, light: bool, options: RasterOptions, timeout: Duration, cancel: &AtomicBool, ) -> Result<Option<Raster>>

Render one diagram off the UI thread. Any error stops and reaps the worker; subsequent calls fail until the application creates a new handle.

pub fn render_with_background( &mut self, source: &str, light: bool, background: Background, options: RasterOptions, timeout: Duration, cancel: &AtomicBool, ) -> Result<Option<Raster>>

Render with an explicit canvas treatment. Transparency is applied before rasterization, preserving antialiased edges and intentional diagram fills. Uses the same limits, cancellation and worker cleanup as Self::render.

Trait Implementations

impl Drop for Worker

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
