Enum FilterExpr 

#[non_exhaustive]
pub enum FilterExpr {
    Empty,
}

Server-side filter expression.

0.1.0 deliberately exposes only Empty. The enum is #[non_exhaustive] and tagged so future filter shapes can be added without breaking the wire format or downstream pattern matchers.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

No filter, accept every row.

Implementations

impl FilterExpr

pub fn empty() -> Self

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for FilterExpr

fn clone(&self) -> FilterExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilterExpr

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

Formats the value using the given formatter.

impl Default for FilterExpr

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FilterExpr

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FilterExpr

fn eq(&self, other: &FilterExpr) -> 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 FilterExpr

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
