Scalar filter operations.

Variants

Equals(T)

Equals the value.

Not(Box<T>)

Not equals the value.

In(Vec<T>)

In a list of values.

NotIn(Vec<T>)

Not in a list of values.

Lt(T)

Less than.

Lte(T)

Less than or equal.

Gt(T)

Greater than.

Gte(T)

Greater than or equal.

Contains(T)

Contains (for strings).

StartsWith(T)

Starts with (for strings).

EndsWith(T)

Ends with (for strings).

IsNull

Is null.

IsNotNull

Is not null.

Implementations

impl<T: Into<FilterValue>> ScalarFilter<T>

pub fn into_filter(self, column: impl Into<FieldName>) -> Filter

Convert to a Filter with the given column name.

The column name can be a static string (zero allocation) or an owned string. For IN/NOT IN filters, uses SmallVec to avoid heap allocation for ≤16 values.

Trait Implementations

impl<T: Clone> Clone for ScalarFilter<T>

fn clone(&self) -> ScalarFilter<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for ScalarFilter<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for ScalarFilter<T>

fn eq(&self, other: &ScalarFilter<T>) -> 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.
