Struct Migration 

pub struct Migration {
    pub version: i64,
    pub description: String,
    pub sql: String,
}

One migration: a version, a description and the SQL text. The text is hashed; changing a migration that has been applied is an error, never a silent re-run.

Fields

version: i64

Positive, strictly increasing across a program’s migrations (sqlx uses the timestamp or sequence in the file name).

description: String

A short description, stored in the ledger.

sql: String

The statements, run in one transaction.
