Convert url scheme to an SqlFamily.

pub fn max_insert_rows(&self) -> Option<usize>

Get the default max rows for a batch insert.

pub fn max_bind_values(&self) -> usize

Get the max number of bind parameters for a single query, which in targets other than Wasm can be controlled with the env var QUERY_BATCH_SIZE.

pub fn default_max_bind_values(&self) -> usize

Get the default max number of bind parameters for a single query.

pub fn scheme_is_supported(url_scheme: &str) -> bool

Check if a family exists for the given scheme.

pub fn is_postgres(&self) -> bool

True, if family is PostgreSQL.

pub fn is_mysql(&self) -> bool

True, if family is MySQL.

pub fn is_sqlite(&self) -> bool

Trait Implementations

impl Clone for SqlFamily

fn clone(&self) -> SqlFamily

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SqlFamily

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

Formats the value using the given formatter.

impl Display for SqlFamily

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

impl PartialEq for SqlFamily

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
