Struct Migration 

pub struct Migration {
    pub version: u32,
    pub name: &'static str,
    pub up_sql: &'static str,
    pub down_sql: &'static str,
    pub online_safe: bool,
}

A checked-in migration. Existing versions are immutable: add a new version instead of editing an applied one, even when the edit appears additive.

Fields

version: u32

name: &'static str

up_sql: &'static str

down_sql: &'static str

online_safe: bool

Whether the UP direction may run while workers and clients continue using the schema. DOWN is always operator-confirmed and offline.
