Warning:
Fauna is decommissioning FQL v4 on June 30, 2025.

This driver is not compatible with FQL v10, the latest version. Fauna accounts created after August 21, 2024 must use FQL v10.
Ensure you migrate existing projects to the official v10 driver by the v4 EOL date: https://github.com/fauna/fauna-dotnet.

For more information, see the v4 end of life (EOL) announcement and related FAQ.

Detailed Description

Methods modeling the FaunaDB query language. This class is intended to be statically imported into your code:

using static FaunaDB.Query.Language;

Each of these methods constructs a Expr, which can then be composed with other methods to form complex expressions.

Expr existsValue = Exists(Ref("some/ref"));
Expr createValue = Create(
Ref("classes/some_class"),
Obj("data",
Obj("some", "field"))
);
static Expr Obj()
Creates a new empty Object value.
static Expr Ref(string @ref)
Creates a ref value from a string.
static Expr Create(Expr classRef, Expr @params)
Creates a new Create expression.
static Expr Exists(Expr @ref, Expr ts=null)
Creates a new Exists expression.
