impl Debug for QueryTuning

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

Formats the value using the given formatter.

impl Default for QueryTuning

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QueryTuning

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
