Struct CreateCollation 

pub struct CreateCollation {
    pub name: String,
    pub locale: String,
    pub provider: Option<String>,
}

Available on native and crate feature database only.

Create a PostgreSQL collation

Collations define how text is sorted and compared in the database.

Example

use reinhardt_db::migrations::operations::postgres::CreateCollation;

let collation = CreateCollation::new("german", "de_DE");

Fields

name: String

The name.

locale: String

The locale.

provider: Option<String>

The provider.

Implementations

impl CreateCollation

pub fn new( name: impl Into<String>, locale: impl Into<String>, ) -> CreateCollation

Create a new collation

Example

use reinhardt_db::migrations::operations::postgres::CreateCollation;

let collation = CreateCollation::new("german", "de_DE");
assert_eq!(collation.name, "german");
assert_eq!(collation.locale, "de_DE");

pub fn with_provider(self, provider: impl Into<String>) -> CreateCollation

Set the collation provider (icu or libc)

pub fn state_forwards(&self, _app_label: &str, _state: &mut ProjectState)

Apply to project state

pub fn database_forwards( &self, _schema_editor: &dyn BaseDatabaseSchemaEditor, ) -> Vec<String>

Generate SQL

Example

use reinhardt_db::migrations::operations::postgres::CreateCollation;
use reinhardt_db::backends::schema::factory::{SchemaEditorFactory, DatabaseType};

let collation = CreateCollation::new("german", "de_DE");
let factory = SchemaEditorFactory::new();
let editor = factory.create_for_database(DatabaseType::PostgreSQL);

let sql = collation.database_forwards(editor.as_ref());
assert_eq!(sql.len(), 1);
assert!(sql[0].contains("CREATE COLLATION"));
assert!(sql[0].contains("german"));

pub fn database_backwards( &self, _schema_editor: &dyn BaseDatabaseSchemaEditor, ) -> Vec<String>

Generate reverse SQL
