Enum DefaultScalarValue

pub enum DefaultScalarValue {
    Int(i32),
    Float(f64),
    String(String),
    Boolean(bool),
}

The default ScalarValue representation in juniper.

These types closely follow the GraphQL specification.

Variants

Int(i32)

Int scalar as a signed 32‐bit numeric non‐fractional value.

Float(f64)

Float scalar as a signed double‐precision fractional values as specified by IEEE 754.

String(String)

String scalar as a textual data, represented as UTF‐8 character sequences.

Boolean(bool)

Boolean scalar as a true or false value.
