Implementations

impl ValueOrComposite

pub fn into_sql<V, E>( self, column_prefix: Option<&str>, convert: &dyn Fn(&str, Value) -> Result<V, E>, ) -> Result<(String, Vec<(String, V)>), E>

Returns SQL query, and a list of (param_name, param_value).

pub fn to_query(&self) -> String

Return a query-string fragment for this filter (no leading ‘&’).

Trait Implementations

impl Clone for ValueOrComposite

fn clone(&self) -> ValueOrComposite

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueOrComposite

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ValueOrComposite

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ValueOrComposite

fn eq(&self, other: &ValueOrComposite) -> 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.
