Trait Patch 

pub trait Patch
where
    Self: Sized + Send + Sync + 'static,
{
    type Table: Table;

    // Required methods
    fn apply_to(self, entity: &mut Self::Table);
    fn patch_row<'a, 'c: 'a>(
        &'a self,
        db: impl Executor<'c, Database = Db> + 'a,
        id: <Self::Table as Table>::Id,
    ) -> impl Future<Output = Result<()>> + Send + 'a;
}

A type which can be used to “patch” a row, updating multiple fields at once.

Required Associated Types

type Table: Table

Required Methods

fn apply_to(self, entity: &mut Self::Table)

Applies the data of this patch to the given entity. This does not persist the change in the database.

fn patch_row<'a, 'c: 'a>( &'a self, db: impl Executor<'c, Database = Db> + 'a, id: <Self::Table as Table>::Id, ) -> impl Future<Output = Result<()>> + Send + 'a

Applies this patch to a row in the database.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
