Intermediate schema - universal format from all language libraries

Fields

version: String

Schema format version

types: Vec<IntermediateType>

GraphQL object types

enums: Vec<IntermediateEnum>

GraphQL enum types

input_types: Vec<IntermediateInputObject>

GraphQL input object types

interfaces: Vec<IntermediateInterface>

GraphQL interface types (per GraphQL spec §3.7)

unions: Vec<IntermediateUnion>

GraphQL union types (per GraphQL spec §3.10)

queries: Vec<IntermediateQuery>

GraphQL queries

mutations: Vec<IntermediateMutation>

GraphQL mutations

subscriptions: Vec<IntermediateSubscription>

GraphQL subscriptions

fragments: Option<Vec<IntermediateFragment>>

GraphQL fragments (reusable field selections)

directives: Option<Vec<IntermediateDirective>>

GraphQL directive definitions (custom directives)

fact_tables: Option<Vec<IntermediateFactTable>>

Analytics fact tables (optional)

aggregate_queries: Option<Vec<IntermediateAggregateQuery>>

Analytics aggregate queries (optional)

observers: Option<Vec<IntermediateObserver>>

Observer definitions (database change event listeners)

custom_scalars: Option<Vec<IntermediateScalar>>

Custom scalar type definitions

Defines custom GraphQL scalar types with validation rules. Custom scalars can be defined in Python, TypeScript, Java, Go, and Rust SDKs, and are compiled into the CompiledSchema’s CustomTypeRegistry.

security: Option<Value>

Security configuration (from fraiseql.toml) Compiled from the security section of fraiseql.toml at compile time. Optional - if not provided, defaults are used.

observers_config: Option<Value>

Observers/event system configuration (from fraiseql.toml).

Contains backend connection settings (redis_url, nats_url, etc.) compiled from the [observers] TOML section. Embedded verbatim into the compiled schema.

federation_config: Option<Value>

Federation configuration (from fraiseql.toml).

Contains Apollo Federation settings and circuit breaker configuration compiled from the [federation] TOML section. Embedded verbatim into the compiled schema.

subscriptions_config: Option<SubscriptionsConfig>

WebSocket subscription configuration (hooks, limits).

Compiled from the [subscriptions] TOML section. Embedded verbatim into the compiled schema for server-side consumption.

validation_config: Option<ValidationConfig>

Query validation config (depth/complexity limits).

Compiled from [validation] in fraiseql.toml. Embedded into the compiled schema for server-side consumption.

debug_config: Option<DebugConfig>

Debug/development configuration.

Compiled from [debug] in fraiseql.toml. Embedded into the compiled schema for server-side consumption.

mcp_config: Option<McpConfig>

MCP (Model Context Protocol) server configuration.

Compiled from [mcp] in fraiseql.toml. Embedded into the compiled schema for server-side consumption.

rest_config: Option<RestConfig>

REST transport configuration.

Compiled from [rest] in fraiseql.toml. Embedded into the compiled schema for server-side consumption.

query_defaults: Option<IntermediateQueryDefaults>

Global auto-param defaults for list queries (injected from TOML by the merger).

Never present in schema.json — populated at compile time from [query_defaults] in fraiseql.toml. Used by the converter to resolve per-query auto_params.

naming_convention: NamingConvention

Naming convention for GraphQL operation names.

Compiled from fraiseql.toml top-level naming_convention setting.

session_variables: Option<SessionVariablesConfig>

Session variable injection configuration.

When populated, the executor calls set_config() before each query and mutation to inject per-request values (JWT claims, HTTP headers, or literals) as PostgreSQL transaction-scoped settings.

Embedded verbatim from the session_variables key in schema.json.

hierarchies_config: Option<HierarchiesConfig>

Hierarchy definitions for ID-based ltree operators.

Compiled from the [hierarchies] TOML section. Maps hierarchy names to table/path_column pairs for subquery generation.

Trait Implementations

impl Clone for IntermediateSchema

fn clone(&self) -> IntermediateSchema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntermediateSchema

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

Formats the value using the given formatter.

impl Default for IntermediateSchema

fn default() -> IntermediateSchema

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for IntermediateSchema

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for IntermediateSchema

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for IntermediateSchema

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
