Struct odbc_api::parameter::Out

pub struct Out<'a, T>(pub &'a mut T);

Wraps a mutable reference. Use this wrapper in order to indicate that a mutable reference should be bound as an output parameter only.

Example

use odbc_api::{Environment, Out, InOut, Nullable, ConnectionOptions};

let env = Environment::new()?;

let mut conn = env.connect(
    "YourDatabase", "SA", "My@Test@Password1",
    ConnectionOptions::default(),
)?;

let mut ret = Nullable::<i32>::null();
let mut param = Nullable::new(7);

conn.execute(
    "{? = call TestParam(?)}",
    (Out(&mut ret), InOut(&mut param)))?;

Tuple Fields

0: &'a mut T

Trait Implementations

impl<'a, T> ParameterTupleElement for Out<'a, T>where T: OutputParameter,

Mutable references wrapped in Out are bound as output parameters.

unsafe fn bind_to( &mut self, parameter_number: u16, stmt: &mut impl Statement ) -> Result<(), Error>

Bind the parameter in question to a specific parameter_number.
