Struct EnumFilter 

pub struct EnumFilter<E> {
    pub equals: Option<E>,
    pub not: Option<Box<EnumFilter<E>>>,
    pub in_list: Option<Vec<E>>,
    pub not_in: Option<Vec<E>>,
}

Filter operators for an enum-typed column.

E is the user-defined enum. Codegen emits impl ToString for Role so the macro’s bare-ident shorthand (role: Admin) flows through.

Fields

equals: Option<E>

column = value

not: Option<Box<EnumFilter<E>>>

Negation.

in_list: Option<Vec<E>>

column IN (...)

not_in: Option<Vec<E>>

column NOT IN (...)

Implementations

impl<E> EnumFilter<E>

pub fn equals(v: E) -> Self

equals: Some(value).

Trait Implementations

impl<E: Clone> Clone for EnumFilter<E>

fn clone(&self) -> EnumFilter<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for EnumFilter<E>

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

Formats the value using the given formatter.

impl<E: Default> Default for EnumFilter<E>

fn default() -> EnumFilter<E>

Returns the “default value” for a type.

impl<'de, E> Deserialize<'de> for EnumFilter<E>

where E: Serialize + for<'de2> Deserialize<'de2>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<E: PartialEq> PartialEq for EnumFilter<E>

fn eq(&self, other: &EnumFilter<E>) -> 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<E: ToString> ScalarFilter for EnumFilter<E>

fn into_filter(self, column: &str) -> Filter

Lower this scalar filter to a runtime Filter keyed by the given column name.

impl<E> Serialize for EnumFilter<E>

where E: Serialize + for<'de2> Deserialize<'de2>,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
