Struct cynic::queries::SelectionBuilder

pub struct SelectionBuilder<'a, SchemaType, VariablesFields> { /* private fields */ }

Builds a SelectionSet for the given SchemaType and VariablesFields

Implementations

impl<'a, SchemaType, VariablesFields> SelectionBuilder<'a, SchemaType, VariablesFields>

pub fn select_flattened_field<FieldMarker, Flattened, FieldType>( &mut self ) -> FieldSelectionBuilder<'_, FieldMarker, Flattened, VariablesFields>

where FieldMarker: Field, FieldType: FlattensInto<Flattened> + IsFieldType<SchemaType::Type>, SchemaType: HasField<FieldMarker>,

Selects a field applying the flattening rules to its type.

Note that the deserialization for this query must also implement these rules if calling this function.

pub fn select_field<FieldMarker, FieldType>( &mut self ) -> FieldSelectionBuilder<'_, FieldMarker, FieldType, VariablesFields>

where FieldMarker: Field, SchemaType: HasField<FieldMarker>, FieldType: IsFieldType<SchemaType::Type>,

Adds the FieldMarker field into this selection, with the given FieldType. Will type error if the field is not applicable or is not of this type.

This returns a FieldSelectionBuilder that can be used to apply arguments, aliases, and to build an inner selection.

pub fn recurse<FieldMarker, FieldType>( &mut self, max_depth: u8 ) -> Option<FieldSelectionBuilder<'_, FieldMarker, FieldType, VariablesFields>>

where FieldMarker: Field, SchemaType: HasField<FieldMarker>, FieldType: Recursable<FieldMarker::Type>,

Recursively selects a field into this selection, with the given FieldMarker and FieldType, up to the given max_depth.

This will return a None if we have reached the max_depth.

pub fn inline_fragment( &mut self ) -> InlineFragmentBuilder<'_, SchemaType, VariablesFields>

Adds an inline fragment to the SelectionSet

pub fn is_feature_enabled(&self, feature: &str) -> bool

Checks if a feature has been enabled for this operation.

QueryFragment implementations can use this to avoid sending parts of queries to servers that aren’t going to understand them.
