[−][src]Trait wundergraph::query_builder::selection::filter::FilterValue

pub trait FilterValue<C> {
    type RawValue: Clone + FromInputValue<WundergraphScalarValue> + FromLookAheadValue + ToInputValue<WundergraphScalarValue>;
    type AdditionalFilter;
}

A fundamental trait marking that a filter could be constructed for a given type

The generic parameter C represents the type of the column (from diesel) For most implementations this should just be generic over all compatible columns

Associated Types

`type RawValue: Clone + FromInputValue<WundergraphScalarValue> + FromLookAheadValue + ToInputValue<WundergraphScalarValue>`

The raw value type

Normally this is the same as Self but there are cases like Option<T> where we want something other (T) as input for our filter operations

`type AdditionalFilter`

A type describing possible additional filters

For some cases a type supports more operations that just the default set (eq, neq, gt, lt, …). In such cases a type representing those additional operations could be specified here. If there are no additional operations just use ()
