Trait ToSql 

pub trait ToSql: Send + Sync {
    // Required methods
    fn encode(&self, buf: &mut BytesMut) -> Result<IsNull, Error>;
    fn oid(&self) -> Oid;
}

A value that can be bound as a query parameter in the binary format.

This trait is object-safe, so &[&dyn ToSql] is the parameter list the macros build. See StaticType for the compile-time type OID.

Required Methods

fn encode(&self, buf: &mut BytesMut) -> Result<IsNull, Error>

Appends the binary representation of this value to buf, without a length prefix.

fn oid(&self) -> Oid

The PostgreSQL type OID of this value.

Dyn Compatibility

This trait is dyn compatible.

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