Struct ObserverCapabilities

Source

pub struct ObserverCapabilities { /* private fields */ }

Expand description

The full capability matrix produced by ObserverCapabilities::negotiate.

Each EventCategory appears exactly once. Phase 1 reports Lifecycle as Supported and the rest as Unavailable.

Implementations§

Source §

impl ObserverCapabilities

Source

pub fn negotiate() -> Self

Negotiate the capability matrix for the current platform.

Phase 1 is platform-agnostic: the portable lifecycle baseline is Supported on Windows, macOS, and Linux, and all syscall-level categories are honestly Unavailable pending Phase 3 backends.

Source

pub fn categories(&self) -> &[CategoryCapability]

Return the capability entries in stable EventCategory::ALL order.

Source

pub fn category(&self, category: EventCategory) -> &CategoryCapability

Look up the capability entry for one category.

Source

pub fn support(&self, category: EventCategory) -> CapabilitySupport

Return the negotiated support level for one category.

Source

pub fn is_supported(&self, category: EventCategory) -> bool

Return whether a category is fully Supported.

where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
