Module graphql 

GraphQL adapter for Vantage.

Talks to a GraphQL endpoint over HTTP. Unlike the REST sibling, this adapter has its own query language (rendered via GraphqlSelect), structured filter conditions (GraphqlCondition), mandatory field projection, and nested selection sets for relationships — closer in shape to the MongoDB or SQL backends than to REST.

Schemas are maintained locally (no introspection); type information flows through the GraphqlType system declared in types. The vista module bridges tables and YAML specs into Vista.

Modules

types

GraphQL Type System for Vantage.

vista

Vista bridge for the GraphQL backend.

Structs

FieldCondition

A single field <op> value clause. Build one with FieldCondition::new.

GraphqlApi

GraphQL HTTP data source. Cheap to clone — the inner ResilientClient is Arc-wrapped.

GraphqlApiBuilder

Builder for GraphqlApi. Use GraphqlApi::builder to start.

GraphqlSelect

GraphQL query builder — produces a query document + variables map.

RenderedQuery

The rendered output of GraphqlSelect::render — what GraphqlApi::post_graphql consumes.

Supports

Per-table overrides for what the server will actually accept, each None meaning “use the dialect’s default”.

Enums

CountMode

How get_count is answered. YAML: count: list | aggregate.

FilterDialect

How a GraphqlCondition is rendered into a GraphQL argument object.

GraphqlCondition

Structured filter for GraphQL requests. Built by the operator trait (GraphqlOperation in operation.rs) and rendered at fetch time.

GraphqlOp

The set of comparison/logical operators a FieldCondition can use.

Traits

GraphqlOperation

GraphQL operators that produce a GraphqlCondition.
