Struct Raised 

pub struct Raised { /* private fields */ }

The one language-neutral exceptional-completion envelope.

Recursive relations such as causes, contexts, groups, and suppressed exceptions belong to guest-owned managed payload objects. They are never fields of this envelope.

Implementations

impl Raised

pub fn new( class: Value, payload: Value, origin: Origin, profile: Symbol, ) -> Result<Raised, Error>

Builds a checked, non-recursive raised envelope.

A raised envelope cannot itself be used as the immediate payload. Guest relation graphs must instead live in their ordinary managed objects.

pub fn class_ref(&self) -> &Value

Returns the kernel class identity used for handler matching.

pub fn payload(&self) -> &Value

Returns the ordinary guest payload value.

pub fn origin(&self) -> &Origin

Returns deterministic source provenance for the raise site.

pub fn profile(&self) -> &Symbol

Returns the stable guest-profile identity used for policy routing.

pub fn browse( &self, cx: &mut Cx, budget: RaisedBrowseBudget, ) -> Result<RaisedBrowseProjection, Error>

Renders the payload under an explicit byte budget and reports loss.

Trait Implementations

impl Clone for Raised

fn clone(&self) -> Raised

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Raised

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

impl Eq for Raised

impl Object for Raised

fn display(&self, cx: &mut Cx) -> Result<String, Error>

Render the object as a human-readable display string.

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

Expose the object for Rust downcasting.

fn header(&self) -> &ObjectHeader

Identity and trust header for the object; defaults to the shared anonymous header.

fn op(&self, _key: &OpKey) -> Option<&dyn Op>

Resolve the operation registered under key, if any.

fn claims( &self, _cx: &mut Cx, _pattern: &ClaimPattern, _sink: &mut dyn ClaimSink, ) -> Result<(), Error>

Emit the object’s claims matching pattern into sink.

fn snapshot(&self, _cx: &mut Cx) -> Result<Option<Datum>, Error>

Optional content-addressable snapshot of the object’s state.

impl ObjectCompat for Raised

fn as_expr(&self, cx: &mut Cx) -> Result<Expr, Error>

Expression form of the object; defaults to an opaque extension node.

fn as_table(&self, cx: &mut Cx) -> Result<Value, Error>

Project the object into a table value; the default exposes its display.

fn as_object_encoder(&self) -> Option<&dyn ObjectEncode>

Object-encoder view, if the object encodes other objects.

fn class(&self, cx: &mut Cx) -> Result<Value, Error>

Class object this value belongs to; defaults to nil.

fn as_callable(&self) -> Option<&dyn Callable>

Callable view, if the object can be invoked.

fn as_class(&self) -> Option<&dyn Class>

Class view, if the object is a class.

fn as_shape(&self) -> Option<&dyn Shape>

Shape view, if the object is a shape.

fn as_read_constructor(&self) -> Option<&dyn ReadConstructor>

Read-constructor view, if the object decodes data forms.

fn as_number_domain(&self) -> Option<&(dyn NumberDomain + 'static)>

Number-domain view, if the object is a number domain.

fn as_number_value(&self) -> Option<&dyn NumberValue>

Number-value view, if the object is a domain number.

fn as_eval_fabric(&self) -> Option<&dyn EvalFabric>

Eval-fabric view, if the object is a distributed eval surface.

fn as_stream(&self) -> Option<&dyn Stream>

Stream view, if the object is a stream.

fn as_sequence(&self) -> Option<&dyn Sequence>

Sequence view, if the object is a sequence.

fn as_thunk(&self) -> Option<&dyn Thunk>

Thunk view, if the object is a deferred computation.

fn as_list(&self) -> Option<&(dyn ListValue + 'static)>

List view, if the object is a list value.

fn as_table_impl(&self) -> Option<&(dyn Table + 'static)>

Table-implementation view, if the object is a table.

fn as_dir(&self) -> Option<&(dyn Dir + 'static)>

Directory view, if the object is a directory.

fn truth(&self, _cx: &mut Cx) -> Result<bool, Error>

Truthiness of the object; defaults to true.

fn publish_shape_satisfaction_claims( &self, _cx: &mut Cx, _shape: &Ref, ) -> Result<bool, Error>

Publish claims asserting that the object satisfies shape; returns whether any were published.

impl ObjectEncode for Raised

fn object_encoding(&self, cx: &mut Cx) -> Result<ObjectEncoding, Error>

Returns the ObjectEncoding this object should be rendered as.

impl PartialEq for Raised

fn eq(&self, other: &Raised) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
