    pub inner: Box<Query>,
}

Counts the number of items returned from a query.

Implementations

impl CountQuery

pub fn new(inner: Box<Query>) -> ValidationResult<Self>

Marks a query as exported.

Arguments

• inner: The query to export.

Trait Implementations

impl Clone for CountQuery

fn clone(&self) -> CountQuery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CountQuery

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

Formats the value using the given formatter.

impl Into<Query> for CountQuery

fn into(self) -> Query

Converts this type into the (usually inferred) input type.

impl PartialEq for CountQuery

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

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

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

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