Trait Implementations

impl Clone for AddVirtualColumnOutputEntry

fn clone(&self) -> AddVirtualColumnOutputEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AddVirtualColumnOutputEntry

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

impl Default for AddVirtualColumnOutputEntry

fn default() -> AddVirtualColumnOutputEntry

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AddVirtualColumnOutputEntry

fn deserialize<__D>( __deserializer: __D, ) -> Result<AddVirtualColumnOutputEntry, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AddVirtualColumnOutputEntry

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

Tests for self and other values to be equal, and is used by ==.

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