Enum Migration 

pub enum Migration<'a> {
    Sql {
        name: &'a str,
        sql: &'a str,
    },
    Fn {
        name: &'a str,
        f: fn(&Connection) -> MigrationFuture<'_>,
    },
}

A single migration step. Can be a raw SQL string, an async function, or a file.

Variants

Fn

Fields

name: &'a str

f: fn(&Connection) -> MigrationFuture<'_>

Implementations

impl<'a> Migration<'a>

pub const fn up(name: &'a str, sql: &'a str) -> Self

Creates a migration from a raw SQL string.

pub const fn up_fn( name: &'a str, f: fn(&Connection) -> MigrationFuture<'_>, ) -> Self

Creates a migration from a rust function. The function must take a &Connection and return a MigrationFuture. Use the up_fn! macro to directly take an async function.

Trait Implementations

impl<'a> Clone for Migration<'a>

fn clone(&self) -> Migration<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
