Trait elephantry::Entity

pub trait Entity {
    pub fn from(tuple: &Tuple<'_>) -> Self;
    pub 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

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

Create a new struct from SQL result.

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

Get the value of the field named field.
