Struct fuel_indexer_schema::db::tables::IndexerSchema
source · 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
impl IndexerSchema
sourcepub fn new(
namespace: &str,
identifier: &str,
schema: &GraphQLSchema,
db_type: DbType
) -> IndexerSchemaDbResult<Self>
pub fn new( namespace: &str, identifier: &str, schema: &GraphQLSchema, db_type: DbType ) -> IndexerSchemaDbResult<Self>
Create a new IndexerSchema
.
sourcepub fn parsed(&self) -> &ParsedGraphQLSchema
pub fn parsed(&self) -> &ParsedGraphQLSchema
Return the associated ParsedGraphQLSchema
.
sourcepub async fn commit(
self,
schema: &GraphQLSchema,
conn: &mut IndexerConnection
) -> IndexerSchemaDbResult<Self>
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
sourcepub async fn load(
pool: &IndexerConnectionPool,
namespace: &str,
identifier: &str
) -> IndexerSchemaDbResult<Self>
pub async fn load( pool: &IndexerConnectionPool, namespace: &str, identifier: &str ) -> IndexerSchemaDbResult<Self>
Load a IndexerSchema
from the database.
