Enum PolicyError 

pub enum PolicyError {
    UnknownName(String),
}

The runtime types that appear in bevy-brink’s own public signatures, re-exported so consumers can name them without depending on brink-runtime: FlowInstance, Program, Choice, Step’s return, RuntimeError’s error, FallbackHandler for the “no bindings” advance path, the scoped story-state types a host needs to build a policy and a per-step routing view (see docs/scoped-flow-state-spec.md): WorldPolicy, Scope, PolicyError, and ContextView (usually built via flow_context_view instead of by hand) — and the per-entity durability types produced/consumed by BrinkGlobals::save_state/load_state and save_flow_state/load_flow_state (F6.3, see the globals module’s “Save/load” docs): SaveState and LoadReport.

World is deliberately absent here — it collides with bevy::prelude::World under a glob import, so it is re-exported under the alias BrinkWorld. Errors resolving a WorldPolicy against a Program’s symbol table.

Resolution happens once, at World creation — an unknown name here is a host configuration error, not a runtime one.

Variants

UnknownName(String)

A name in WorldPolicy::overrides matched neither a declared global variable nor a resolvable knot/stitch path.

Trait Implementations

impl Clone for PolicyError

fn clone(&self) -> PolicyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolicyError

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

Formats the value using the given formatter.

impl Eq for PolicyError

impl Error for PolicyError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for PolicyError

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

Equality operator ==.

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

Inequality operator !=.
