Struct MigrationStep 

pub struct MigrationStep {
    pub step_number: usize,
    pub operation: MigrationOperation,
    pub description: String,
    pub reversible: bool,
    pub dependencies: Vec<usize>,
}

A single step in a migration plan

Fields

step_number: usize

Step number (for ordering)

operation: MigrationOperation

Operation to perform

description: String

Description of what this step does

reversible: bool

Whether this step can be rolled back

dependencies: Vec<usize>

Dependencies on other steps (must complete before this step)

Trait Implementations

impl Clone for MigrationStep

fn clone(&self) -> MigrationStep

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MigrationStep

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MigrationStep

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for MigrationStep

impl PartialEq for MigrationStep

fn eq(&self, other: &MigrationStep) -> 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 Serialize for MigrationStep

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
