Trait Implementations

impl AsRef<Expr> for AggExpr

fn as_ref(&self) -> &Expr

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for AggExpr

fn clone(&self) -> AggExpr

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

impl<'de> Deserialize<'de> for AggExpr

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where
__D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer. Read more

impl From<AggExpr> for Expr

fn from(agg: AggExpr) -> Self

Converts to this type from the input type.

impl PartialEq<AggExpr> for AggExpr

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

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

1.0.0 · source

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. Read more
