}

Variants

Clickhouse = 0

Postgres = 1

Implementations

impl SqlQueryBackend

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of SqlQueryBackend.

pub fn from_i32(value: i32) -> Option<SqlQueryBackend>

👎Deprecated:

Use the TryFrom<i32> implementation instead

Converts an i32 to a SqlQueryBackend, or None if value is not a valid variant.

impl SqlQueryBackend

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for SqlQueryBackend

fn clone(&self) -> SqlQueryBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SqlQueryBackend

impl Debug for SqlQueryBackend

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

impl Eq for SqlQueryBackend

impl From<SqlQueryBackend> for i32

fn from(value: SqlQueryBackend) -> i32

impl Hash for SqlQueryBackend

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SqlQueryBackend
