Implementations

impl ViewConfig

pub fn reset(&mut self, reset_expressions: bool)

pub fn apply_update(&mut self, update: ViewConfigUpdate) -> bool

Apply ViewConfigUpdate to a ViewConfig, ignoring any fields in update which were unset.

pub fn is_aggregated(&self) -> bool

pub fn is_column_expression_in_use(&self, name: &str) -> bool

pub fn is_equivalent(&self, other: &Self) -> bool

ViewConfig carries additional metadata in the form of None columns which are filtered befor ebeing passed to the engine, but whose position is a placeholder for Viewer functionality. is_equivalent tests equivalency from the perspective of the engine.

Trait Implementations

impl Clone for ViewConfig

fn clone(&self) -> ViewConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ViewConfig

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

Formats the value using the given formatter.

impl Default for ViewConfig

fn default() -> ViewConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ViewConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ViewConfig> for ViewConfigUpdate

fn from(value: ViewConfig) -> Self

Converts to this type from the input type.

impl From<ViewConfigUpdate> for ViewConfig

fn from(value: ViewConfigUpdate) -> Self

Converts to this type from the input type.

impl PartialEq for ViewConfig

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

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

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

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

impl Serialize for ViewConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
