Struct MigrationRegistryKey 

pub struct MigrationRegistryKey { /* private fields */ }

MigrationRegistryKey

MigrationRegistryKey names one completed schema migration by canonical migration identity plus monotonic version. The registry uses this key to reject repeat execution before the lower migration engine is invoked.

Implementations

impl MigrationRegistryKey

pub const fn new(migration_id: EntityName, version: u64) -> Self

Build one registry key from canonical migration identity.

pub const fn migration_id(self) -> EntityName

Return the canonical migration identity.

pub const fn version(self) -> u64

Return the monotonic migration version.

Trait Implementations

impl Clone for MigrationRegistryKey

fn clone(&self) -> MigrationRegistryKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MigrationRegistryKey

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

Formats the value using the given formatter.

impl Ord for MigrationRegistryKey

fn cmp(&self, other: &MigrationRegistryKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MigrationRegistryKey

fn eq(&self, other: &MigrationRegistryKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for MigrationRegistryKey

fn partial_cmp(&self, other: &MigrationRegistryKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
