[][src]Struct diesel::pg::PgConnection

pub struct PgConnection { /* fields omitted */ }

The connection string expected by PgConnection::establish should be a PostgreSQL connection string, as documented at https://www.postgresql.org/docs/9.4/static/libpq-connect.html#LIBPQ-CONNSTRING

Methods

impl PgConnection[src]

pub fn build_transaction(&self) -> TransactionBuilder[src]
