Struct MigrationStep 

pub struct MigrationStep {
    pub version: i64,
    pub description: &'static str,
}

A single forward-only migration step.

The struct intentionally does not contain the SQL itself — each backend defines its own step list as &[(i64, &str, &str)] tuples of (version, description, sql).

Fields

version: i64

Monotonically increasing version number, starting at 1.

description: &'static str

Human-readable description of what this step does.
