pub fn try_from_expr(plan: &Expr) -> Result<&Subquery>

Trait Implementations

impl Clone for Subquery

fn clone(&self) -> Subquery

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Subquery

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

Formats the value using the given formatter.

impl Hash for Subquery

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

Feeds this value into the given Hasher.

fn hash_slice<H: Hasher>(_data: &[Self], state: &mut H)where
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Subquery> for Subquery

fn eq(&self, _other: &Self) -> bool

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

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.
