Trait elephantry::entity::Entity

pub trait Entity {
    // Required methods
    fn from(tuple: &Tuple<'_>) -> Self;
    fn get(&self, field: &str) -> Option<&dyn ToSql>;
}

Trait to translate SQL row to struct and vice versa.

You probably should use the Entity derive macro instead of writing the impl by yourself.

Required Methods

fn from(tuple: &Tuple<'_>) -> Self

Create a new struct from SQL result.

fn get(&self, field: &str) -> Option<&dyn ToSql>

Get the value of the field named field.

Object Safety

This trait is not object safe.
