Struct Migration 

pub struct Migration {
    pub id: String,
    pub dependencies: Vec<String>,
    pub operations: Vec<Operation>,
    pub atomic: bool,
}

A single migration: an ordered, dependency-aware set of operations. id is derived from the filename at load time and is not stored in the file.

Fields

id: String

dependencies: Vec<String>

operations: Vec<Operation>

atomic: bool

When false, this migration runs outside a transaction. Required for operations that cannot run inside a transaction (e.g. CREATE INDEX CONCURRENTLY). Defaults to true so existing migration files are unaffected.

Implementations

impl Migration

pub fn from_yaml_str(s: &str) -> Result<Self, Error>

pub fn to_yaml_string(&self) -> Result<String, Error>

pub fn get_entities(&self) -> HashSet<(EntityKind, String)>

Returns the set of top-level entities touched by this migration. Includes FK target tables so callers can detect cross-namespace references.

impl Clone for Migration

fn clone(&self) -> Migration

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Migration

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Migration

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Migration

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
