Trait odbc_api::parameter::ParameterRef

pub unsafe trait ParameterRef {
    unsafe fn bind_to(
        &mut self, 
        parameter_number: u16, 
        stmt: &mut impl Statement
    ) -> Result<(), Error>;
}

Implementers of this trait can be used as individual parameters of in a crate::ParameterRefCollection. They can be bound as either input parameters, output parameters or both.

Safety

Parameters bound to the statement must remain valid for the lifetime of the instance.

Required Methods

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.

Safety

Since the parameter is now bound to stmt callers must take care that it is ensured that the parameter remains valid while it is used. If the parameter is bound as an output parameter it must also be ensured that it is exclusively referenced by statement.
