Enum HealthSignal 

pub enum HealthSignal {
    IngestionLag,
    RingOverflow,
    FederationTimeout,
    YubabaRaftQuorumLost,
}

Scryer substrate health condition that tower can predicate over.

These signals come from scryer’s own self-monitoring emissions rather than from service event streams. Allows tower to react to observability infrastructure failures as well as application-level events.

Variants

IngestionLag

Scryer ingestion is falling behind the event producer rate.

RingOverflow

The in-memory ring buffer has overflowed and events are being dropped.

FederationTimeout

A federated query to a peer scryer timed out.

YubabaRaftQuorumLost

Yubaba’s raft consensus has lost quorum (fewer than ⌊N/2⌋+1 peers reachable). The first canonical tower rule targets this signal.

Trait Implementations

impl StructuralPartialEq for HealthSignal

impl TS for HealthSignal

const DOCS: Option<&'static str>

JSDoc comment to describe this type in TypeScript - when TS is derived, docs are automatically read from your doc comments or #[doc = ".."] attributes

type WithoutGenerics = HealthSignal

If this type does not have generic parameters, then WithoutGenerics should just be Self. If the type does have generic parameters, then all generic parameters must be replaced with a dummy type, e.g ts_rs::Dummy or (). The only requirement for these dummy types is that EXPORT_TO must be None.

fn ident() -> String

Identifier of this type, excluding generic parameters.

fn name() -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete() -> String

Declaration of this type using the supplied generic arguments. The resulting TypeScript definition will not be generic. For that, see TS::decl(). If this type is not generic, then this function is equivalent to TS::decl().

fn decl() -> String

Declaration of this type, e.g. type User = { user_id: number, ... }. This function will panic if the type has no declaration.

fn inline() -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened() -> String

Flatten a type declaration.
This function will panic if the type cannot be flattened.

fn visit_generics(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all type parameters of this type.

fn output_path() -> Option<&'static Path>

Returns the output path to where T should be exported.
The returned path does not include the base directory from TS_RS_EXPORT_DIR.

fn visit_dependencies(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all dependency of this type.

fn dependencies() -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem. To export this type together with all of its dependencies, use TS::export_all.

fn export_all() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_all_to(out_dir: impl AsRef<Path>) -> Result<(), ExportError>

where Self: 'static,

Manually export this type into the given directory, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_to_string() -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String.
This function does not format the output, even if the format feature is enabled.

fn default_output_path() -> Option<PathBuf>

Returns the output path to where T should be exported.
