Struct MigrationFile 

pub struct MigrationFile {
    pub id: String,
    pub onto: String,
    pub squashed: Vec<String>,
    pub filename: String,
    pub body: String,
}

A parsed migration file.

Fields

id: String

Full migration ID: a version prefix (m2, or m1 for a file written before the format change) + 38 hex chars.

onto: String

Parent’s full ID, or the literal string "initial".

squashed: Vec<String>

IDs this migration squashes (§12); empty for normal migrations.

filename: String

Original filename (stem only, e.g. 00001_m2a3f9bc12de4).

body: String

Everything after the two header lines.

Implementations

impl MigrationFile

pub fn short_id(&self) -> &str

Short ID used in filenames — the leading prefix of id, whose length depends on which format wrote the file: m1 carried 6 hex chars, m2 carries 12 (see compute_short_id).

pub fn is_first(&self) -> bool

Whether this is the “first” migration (onto == “initial”).
