pub struct QueryBuilder<'schema, 'fragreg>(/* private fields */);

Implementations

impl<'schema: 'fragreg, 'fragreg> QueryBuilder<'schema, 'fragreg>

pub fn add_directive( self, annot: DirectiveAnnotation, ) -> Result<Self, QueryBuildError>

Add a DirectiveAnnotation after any previously added DirectiveAnnotations.

pub fn add_selection( self, selection: Selection<'schema>, ) -> Result<Self, QueryBuildError>

Add a Selection after any previously added Selections.

pub fn add_variable(self, variable: Variable) -> Result<Self, QueryBuildError>

Add a Variable after any previously added Variables.

pub fn build(self) -> Result<Query<'schema, 'fragreg>, QueryBuildError>

Consume this QueryBuilder to produce a Query.

pub fn build_from_ast( schema: &'schema Schema, fragment_registry: &'fragreg FragmentRegistry<'schema>, ast: &Query, file_path: Option<&Path>, ) -> Result<Query<'schema, 'fragreg>, QueryBuildError>

Produce a Query from a ast::operation::Query.

pub fn build_from_file( schema: &'schema Schema, fragment_registry: &'fragreg FragmentRegistry<'schema>, file_path: impl AsRef<Path>, ) -> Result<Query<'schema, 'fragreg>, QueryBuildError>

Produce a Query from a file on disk that whose contents contain an executable document with only a single query defined in it.

If multiple operations are defined in the document, an error will be returned. For cases where multiple operations may be defined in a single document, use ExecutableDocumentBuilder.

If the document contents include any fragment definitions, an error will be returned. For cases where operations and fragments may be defined together in a single document, use ’ExecutableDocumentBuilder`.

pub fn build_from_str( schema: &'schema Schema, fragment_registry: &'fragreg FragmentRegistry<'schema>, file_path: Option<&Path>, content: impl AsRef<str>, ) -> Result<Query<'schema, 'fragreg>, QueryBuildError>

Produce a Query from a string whose contents contain a document with only a single query defined in it.

If multiple operations are defined in the document, an error will be returned. For cases where multiple operations may be defined in a single document, use ExecutableDocumentBuilder.

If the document contents include any fragment definitions, an error will be returned. For cases where operations and fragments may be defined together in a single document, use ’ExecutableDocumentBuilder`.

pub fn from_ast( schema: &'schema Schema, fragment_registry: &'fragreg FragmentRegistry<'schema>, ast: &Query, file_path: Option<&Path>, ) -> Result<Self, QueryBuildError>

Produce a QueryBuilder from a Query.

pub fn from_file( schema: &'schema Schema, fragment_registry: &'fragreg FragmentRegistry<'schema>, file_path: impl AsRef<Path>, ) -> Result<Self, QueryBuildError>

Produce a QueryBuilder from a file on disk that whose contents contain an executable document with only a single query defined in it.

If multiple operations are defined in the document, an error will be returned. For cases where multiple operations may be defined in a single document, use ExecutableDocumentBuilder.

If the document contents include any fragment definitions, an error will be returned. For cases where operations and fragments may be defined together in a single document, use ’ExecutableDocumentBuilder`.

pub fn from_str( schema: &'schema Schema, fragment_registry: &'fragreg FragmentRegistry<'schema>, content: impl AsRef<str>, file_path: Option<&Path>, ) -> Result<Self, QueryBuildError>

Produce a QueryBuilder from a string whose contents contain a document with only a single query defined in it.

If multiple operations are defined in the document, an error will be returned. For cases where multiple operations may be defined in a single document, use ExecutableDocumentBuilder.

If the document contents include any fragment definitions, an error will be returned. For cases where operations and fragments may be defined together in a single document, use ’ExecutableDocumentBuilder`.

pub fn new( schema: &'schema Schema, fragment_registry: &'fragreg FragmentRegistry<'schema>, ) -> Self

See [OperationBuilderTrait::new]

pub fn set_directives( self, directives: &[DirectiveAnnotation], ) -> Result<Self, QueryBuildError>

Set the list of DirectiveAnnotations.

NOTE: If any previous directives were added (either using this function or QueryBuilder::add_directive()), they will be fully replaced by the DirectiveAnnotations passed here.

pub fn set_name(self, name: Option<String>) -> Result<Self, QueryBuildError>

Set the name of the Query.

pub fn set_variables( self, variables: Vec<Variable>, ) -> Result<Self, QueryBuildError>

Set the list of Variables.

NOTE: If any previous variables were added (either using this function or QueryBuilder::add_variable()), they will be fully replaced by the collection of variables passed here.

Trait Implementations

impl<'schema, 'fragreg> Clone for QueryBuilder<'schema, 'fragreg>

fn clone(&self) -> QueryBuilder<'schema, 'fragreg>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'schema, 'fragreg> Debug for QueryBuilder<'schema, 'fragreg>

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

Formats the value using the given formatter.

impl<'schema, 'fragreg> PartialEq for QueryBuilder<'schema, 'fragreg>

fn eq(&self, other: &QueryBuilder<'schema, 'fragreg>) -> 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.
