Trait ToParams 

pub trait ToParams {
    // Required methods
    fn param_count(&self) -> usize;
    fn natural_oids(&self) -> Vec<Oid> ;
    fn encode(&self, target_oids: &[Oid], buf: &mut Vec<u8>) -> Result<()>;
}

Trait for encoding multiple parameters.

Required Methods

fn param_count(&self) -> usize

Number of parameters.

fn natural_oids(&self) -> Vec<Oid>

Get natural OIDs for all parameters (for exec_* with SQL string).

fn encode(&self, target_oids: &[Oid], buf: &mut Vec<u8>) -> Result<()>

Encode all parameters using specified target OIDs.

The target_oids slice must have the same length as param_count(). Each parameter is encoded using its preferred format based on the OID.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
