Struct Postgres 

pub struct Postgres { /* private fields */ }

Implementations

impl Postgres

pub fn connect(url: &str, tls: Option<&dyn Tls>) -> Result<Self, String>

tls is None in ironwork’s own build, which then connects without TLS.

pub fn source(&self) -> &str

The server and database, as a recording’s header names them.

Trait Implementations

impl Database for Postgres

fn execute(&mut self, call: &Call<'_>) -> Answer

Two rows are enough to tell a SELECT INTO’s one row from its too many.

fn open(&mut self, call: &Call<'_>) -> Answer

fn fetch(&mut self, call: &Call<'_>) -> Answer

One row, or no row at the end.

fn close(&mut self, call: &Call<'_>) -> Answer

fn commit(&mut self, _: &Call<'_>) -> Answer

fn rollback(&mut self, _: &Call<'_>) -> Answer

fn close_all(&mut self) -> Result<(), Abandoned>

Closes every cursor, held ones too, as the end of a CICS task does, so the next task on the same connection finds none open. A backend without cursors of its own has nothing to close.
