pub struct IndexerSchema { /* private fields */ }
Expand description

IndexerSchema is used to encapsulate most of the logic related to parsing GraphQL types, generating SQL from those types, and committing that SQL to the database.

Implementations§

source§

impl IndexerSchema

source

pub fn new( namespace: &str, identifier: &str, schema: &GraphQLSchema, db_type: DbType ) -> IndexerSchemaDbResult<Self>

Create a new IndexerSchema.

source

pub fn parsed(&self) -> &ParsedGraphQLSchema

Return the associated ParsedGraphQLSchema.

source

pub async fn commit( self, schema: &GraphQLSchema, conn: &mut IndexerConnection ) -> IndexerSchemaDbResult<Self>

Generate table SQL for each indexable object in the given GraphQL schema.

Ideally all of these queries should return the objects that they persist to the DB (e.g., INSERT .. RETURNING *).

TODO: We should also be caching as much of this IndexerSchema as possible

source

pub async fn load( pool: &IndexerConnectionPool, namespace: &str, identifier: &str ) -> IndexerSchemaDbResult<Self>

Load a IndexerSchema from the database.
