Implementations

impl Migration

pub fn unapplied(input_name: &str, sql: &str) -> Result<Migration, Error>

Create an unapplied migration, name and version are parsed from the input_name, which must be named in the format (U|V){1}__{2}.rs where {1} represents the migration version and {2} the name.

pub fn version(&self) -> u32

Get the Migration version

pub fn prefix(&self) -> &Type

Get the Prefix

pub fn name(&self) -> &str

Get the Migration Name

pub fn applied_on(&self) -> Option<&DateTime<Local>>

Get the Migration Name

pub fn checksum(&self) -> u64

Get the Migration checksum. Checksum is formed from the name version and sql of the Migration
