Trait ModelBuilder 

pub trait ModelBuilder<'a, DB>
where
    Self: Sized + Send + Sync,
    DB: Database,
{
    type Model;

    // Required methods
    fn insert<'e: 'a, E>(self, db: E) -> BoxFuture<'a, Result<Self::Model>>
       where E: 'e + Executor<'e, Database = DB>;
    fn update<'e: 'a, E>(self, db: E) -> BoxFuture<'a, Result<Self::Model>>
       where E: 'e + Executor<'e, Database = DB>;
    fn modified_fields(&self) -> Vec<&'static str>;
    fn build(self) -> Self::Model;
}

A struct that implements ModelBuilder implements the builder pattern for a model.

Required Associated Types

type Model

Required Methods

fn insert<'e: 'a, E>(self, db: E) -> BoxFuture<'a, Result<Self::Model>>

where E: 'e + Executor<'e, Database = DB>,

fn update<'e: 'a, E>(self, db: E) -> BoxFuture<'a, Result<Self::Model>>

where E: 'e + Executor<'e, Database = DB>,

fn modified_fields(&self) -> Vec<&'static str>

All fields that will be modified in the query.

fn build(self) -> Self::Model

Build the model, don’t insert or update it.

This trait is not dyn compatible.

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