Implementations

impl Ella

pub async fn shutdown(self) -> Result<()>

pub async fn query(&self, sql: impl AsRef<str>) -> Result<Lazy>

pub async fn execute(&self, sql: impl AsRef<str>) -> Result<()>

Execute a SQL statement on the datastore.

This is shorthand for self.query("<cmd>").execute().

pub fn table<'a>(&'a self, table: impl Into<TableRef<'a>>) -> GetTable<'a>

pub fn catalog<'a>(&'a self, catalog: impl Into<Id<'a>>) -> GetCatalog<'a>

pub fn schema<'a>(&'a self, schema: impl Into<SchemaRef<'a>>) -> GetSchema<'a>

pub async fn use_catalog<'a>(self, catalog: impl Into<Id<'a>>) -> Result<Self>

Set catalog as the default catalog for the current context.

This is broadly equivalent to the SQL statement USE CATALOG <catalog>.

pub async fn use_schema<'a>(self, schema: impl Into<Id<'a>>) -> Result<Self>

Set schema as the default schema for the current context.

This is broadly equivalent to the SQL statement USE SCHEMA <schema>.

pub fn config(&self) -> Config

pub fn default_catalog(&self) -> Id<'static>

pub fn default_schema(&self) -> Id<'static>
