Implementations

impl Migration

pub fn new<IN, ISD, ISU>(
    version: i32,
    name: IN,
    sql_up: ISU,
    sql_down: ISD
) -> Self where
    IN: Into<String>,
    ISD: Into<String>,
    ISU: Into<String>, 

Creates a new instance from all necessary input parameters.

pub fn checksum(&self) -> &str

Checksum

Example

use oapth::doc_tests::migration;
assert_eq!(migration().checksum(), "10126747658053090972")

pub fn name(&self) -> &str

Name

Example

use oapth::doc_tests::migration;
assert_eq!(migration().name(), "create_author")

pub fn sql_down(&self) -> &str

Raw SQL for rollbacks

Example

use oapth::doc_tests::migration;
assert_eq!(migration().sql_down(), "DROP TABLE author");

pub fn sql_up(&self) -> &str

Raw SQL for migrations

Example

use oapth::doc_tests::migration;
let mg = assert_eq!(
  migration().sql_up(),
  "CREATE TABLE author (id INT NOT NULL PRIMARY KEY, name VARCHAR(50) NOT NULL)"
);

pub fn version(&self) -> i32

Migration version

Example

use oapth::doc_tests::migration;
assert_eq!(migration().version(), 1)

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

Formats the value using the given formatter.

impl Eq for Migration

impl Ord for Migration

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

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Migration> for Migration

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<Migration> for Migration

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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