Struct SqlMigration 

pub struct SqlMigration {
    pub version: DbVersion,
    pub alterations: String,
    pub fallback_distribution_version: Option<String>,
}

Represent a file containing SQL structure or data alterations.

Fields

version: DbVersion

The semver version this migration targets.

alterations: String

SQL statements to alter the database.

fallback_distribution_version: Option<String>

The distribution version the user can fallback to in order to update their database before updating to the latest node.

Implementations

impl SqlMigration

pub fn new<T: Into<String>>(version: DbVersion, alteration: T) -> Self

Create a new SQL migration instance.

pub fn new_squashed<T: Into<String>>( version: DbVersion, fallback_distribution_version: T, alteration: T, ) -> Self

Create a new squashed SQL migration instance with the fallback distribution version.

Trait Implementations

impl Clone for SqlMigration

fn clone(&self) -> SqlMigration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlMigration

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

Formats the value using the given formatter.

impl Ord for SqlMigration

fn cmp(&self, other: &Self) -> 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 SqlMigration

fn eq(&self, other: &Self) -> 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 SqlMigration

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