Enum MigrationType 

pub enum MigrationType {
    Simple,
    ReversibleUp,
    ReversibleDown,
}

Available on crate feature migrate only.

Migration Type represents the type of migration

Variants

Simple

Simple migration are single file migrations with no up / down queries

ReversibleUp

ReversibleUp migrations represents the add or update part of a reversible migrations It is expected the every migration of this type will have a corresponding down file

ReversibleDown

ReversibleDown migrations represents the delete or downgrade part of a reversible migrations It is expected the every migration of this type will have a corresponding up file

Trait Implementations

impl Clone for MigrationType

fn clone(&self) -> MigrationType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MigrationType

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

Formats the value using the given formatter.

impl Ord for MigrationType

fn cmp(&self, other: &MigrationType) -> 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 MigrationType

fn eq(&self, other: &MigrationType) -> 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 MigrationType

fn partial_cmp(&self, other: &MigrationType) -> 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.
