Struct c3p0_postgres::PgC3p0Json

pub struct PgC3p0Json<Id: IdType, DbId: PostgresIdType, Data: DataType, CODEC: JsonCodec<Data>> { /* private fields */ }

Implementations

impl<Id: IdType, DbId: PostgresIdType, Data: DataType, CODEC: JsonCodec<Data>> PgC3p0Json<Id, DbId, Data, CODEC>

pub fn queries(&self) -> &Queries

pub fn to_model(&self, row: &Row) -> Result<Model<Id, Data>, Box<dyn Error>>

pub async fn fetch_one_optional_with_sql( &self, tx: &mut PgTx, sql: &str, params: &[&(dyn ToSql + Sync)] ) -> Result<Option<Model<Id, Data>>, C3p0Error>

Allows the execution of a custom sql query and returns the first entry in the result set. For this to work, the sql query:

• must be a SELECT
• must declare the ID, VERSION and Data fields in this exact order

pub async fn fetch_one_with_sql( &self, tx: &mut PgTx, sql: &str, params: &[&(dyn ToSql + Sync)] ) -> Result<Model<Id, Data>, C3p0Error>

Allows the execution of a custom sql query and returns the first entry in the result set. For this to work, the sql query:

• must be a SELECT
• must declare the ID, VERSION and Data fields in this exact order

pub async fn fetch_all_with_sql( &self, tx: &mut PgTx, sql: &str, params: &[&(dyn ToSql + Sync)] ) -> Result<Vec<Model<Id, Data>>, C3p0Error>

Allows the execution of a custom sql query and returns all the entries in the result set. For this to work, the sql query:

• must be a SELECT
• must declare the ID, VERSION and Data fields in this exact order
