lib.rs:

(Website reference) The EdgeDB protocol for Edgedb-Rust.

EdgeDB types used for data modeling can be seen on the model crate, in which the Value enum provides the quickest overview of all the possible types encountered using the client. Many of the variants hold Rust standard library types while others contain types defined in this protocol. Some types such as Duration appear to be standard library types but are unique to the EdgeDB protocol.

Other parts of this crate pertain to the rest of the EdgeDB protocol (e.g. client + server message formats), plus various traits for working with the client such as:

• QueryArg: a single argument for a query
• QueryArgs: a tuple of query arguments
• Queryable: for the Queryable derive macro
• QueryResult: single result from a query (scalars and tuples)

The Value enum:

pub enum Value {
Nothing,
Uuid(Uuid),
Str(String),
Bytes(Bytes),
Int16(i16),
Int32(i32),
Int64(i64),
Float32(f32),
Float64(f64),
BigInt(BigInt),
ConfigMemory(ConfigMemory),
Decimal(Decimal),
Bool(bool),
Datetime(Datetime),
LocalDatetime(LocalDatetime),
LocalDate(LocalDate),
LocalTime(LocalTime),
Duration(Duration),
RelativeDuration(RelativeDuration),
DateDuration(DateDuration),
Json(Json),
Set(Vec<Value>),
Object {
shape: ObjectShape,
fields: Vec<Option<Value>>,
},
SparseObject(SparseObject),
Tuple(Vec<Value>),
NamedTuple {
shape: NamedTupleShape,
fields: Vec<Value>,
},
Array(Vec<Value>),
Enum(EnumValue),
Range(Range<Box<Value>>),
}
