Crate sentry_options_validation 

Schema validation library for sentry-options.

Schemas are loaded once into a SchemaRegistry and shared via Arc. Values are validated against schemas as complete objects.

Values refresh lazily on read on the same thread. A read past the staleness window re-reads the values directory on the calling thread and publishes the new snapshot via ArcSwap (last-writer-wins). The full scheme is in docs/architecture.md; the memory-ordering invariants are documented inline in the refresh method below.

Structs

NamespaceSchema

Schema for a namespace, containing validator and option metadata

OptionMetadata

Metadata for a single option in a namespace schema

SchemaRegistry

Registry for loading and storing schemas

ValuesStore

Validates and serves option values, reloading them lazily on read and serving the current snapshot lock-free via ArcSwap. See refresh for the staleness window and memory-ordering details.

Enums

ValidationError

Errors that can occur during schema and value validation

Constants

LOCAL_OPTIONS_DIR

Local fallback path for development

OPTIONS_DIR_ENV

Environment variable to override options directory

OPTIONS_SUPPRESS_MISSING_DIR_ENV

Environment variable to suppress missing directory errors

PRODUCTION_OPTIONS_DIR

Production path where options are deployed via config map

Functions

resolve_options_dir

Resolve options directory using fallback chain:

validate_k8s_name_component

Validate a name component is valid for K8s (lowercase alphanumeric, ‘-’, ‘.’)

Type Aliases

PropagationCallback

Callback invoked when a namespace’s values are updated. Receives (namespace, delay_secs) — the propagation delay from ConfigMap generation to the app reading the new values.

ValidationResult

Result type for validation operations

ValuesByNamespace

A map of option values keyed by their namespace
