Struct ExecutionContext 

pub struct ExecutionContext { /* private fields */ }

Observes progress and allows cooperative cancellation of long-running boolean evaluations. See the module docs for usage.

Implementations

impl ExecutionContext

pub fn new() -> Self

Create a fresh, un-cancelled context with zero progress.

pub fn cancel(&self)

Request cancellation of any in-flight evaluation observing this context. Sticky: once called, is_cancelled returns true for the rest of the context’s lifetime.

pub fn is_cancelled(&self) -> bool

Returns true if cancel has been called.

pub fn progress(&self) -> f64

Progress of an in-flight evaluation as a fraction in [0.0, 1.0]. Meaningful only after this context has been attached to a manifold via Manifold::with_context and an eager op has started. For an unattached context, upstream reads 1.0 (“nothing in flight, complete”).

Trait Implementations

impl Default for ExecutionContext

fn default() -> Self

Returns the “default value” for a type.

impl Drop for ExecutionContext

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.

impl Send for ExecutionContext
