Struct Database 

pub struct Database { /* private fields */ }

The main database interface.

Provides methods for:

• Creating and dropping tables
• CRUD operations (insert, select, update, delete)
• Transaction management
• Observable queries

Implementations

impl Database

pub fn new(name: &str) -> Self

Creates a new database instance.

pub async fn create(name: &str) -> Result<Database, JsValue>

Async factory method for creating a database (for WASM compatibility).

pub fn name(&self) -> String

Returns the database name.

pub fn create_table(&self, name: &str) -> JsTableBuilder

Creates a new table builder.

pub fn register_table(&self, builder: &JsTableBuilder) -> Result<(), JsValue>

Registers a table schema with the database.

pub fn table(&self, name: &str) -> Option<JsTable>

Gets a table reference by name.

pub fn drop_table(&self, name: &str) -> Result<(), JsValue>

Drops a table from the database.

pub fn table_names(&self) -> Array

Returns all table names.

pub fn table_count(&self) -> usize

Returns the number of tables.

pub fn select(&self, columns: &JsValue) -> SelectBuilder

Starts a SELECT query. Accepts either:

• A single string: select(‘*’) or select(‘name’)
• Multiple strings: select(‘name’, ‘score’) - passed as variadic args

pub fn insert(&self, table: &str) -> InsertBuilder

Starts an INSERT operation.

pub fn update(&self, table: &str) -> UpdateBuilder

Starts an UPDATE operation.

pub fn delete(&self, table: &str) -> DeleteBuilder

Starts a DELETE operation.

pub fn transaction(&self) -> JsTransaction

Begins a new transaction.

pub fn clear(&self)

Clears all data from all tables.

pub fn clear_table(&self, name: &str) -> Result<(), JsValue>

Clears data from a specific table.

pub fn total_row_count(&self) -> usize

Returns the total row count across all tables.

pub fn has_table(&self, name: &str) -> bool

Checks if a table exists.

Trait Implementations

impl From<Database> for JsValue

fn from(value: Database) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Database

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for Database

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for Database

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<Database>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for Database

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for Database

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for Database

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<Database>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for Database

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<Database>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for Database

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.

impl VectorFromWasmAbi for Database

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[Database]>

impl VectorIntoWasmAbi for Database

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi(vector: Box<[Database]>) -> Self::Abi

impl WasmDescribe for Database

fn describe()

impl WasmDescribeVector for Database

fn describe_vector()

impl SupportsInstanceProperty for Database
