Struct IntermediateScalar 

pub struct IntermediateScalar {
    pub name: String,
    pub description: Option<String>,
    pub specified_by_url: Option<String>,
    pub validation_rules: Vec<ValidationRule>,
    pub base_type: Option<String>,
}

Custom scalar type definition in intermediate format.

Custom scalars allow applications to define domain-specific types with validation. Scalars are defined in language SDKs (Python, TypeScript, Java, Go, Rust) and compiled into the schema.

Example JSON

{
  "name": "Email",
  "description": "Valid email address",
  "specified_by_url": "https://tools.ietf.org/html/rfc5322",
  "base_type": "String",
  "validation_rules": [
    {
      "type": "pattern",
      "value": {
        "pattern": "^[a-z0-9._%+-]+@[a-z0-9.-]+\\.[a-z]{2,}$"
      }
    }
  ]
}

Fields

name: String

Scalar name (e.g., “Email”, “Phone”, “ISBN”)

description: Option<String>

Scalar description

specified_by_url: Option<String>

URL to specification/RFC (GraphQL spec §3.5.1)

validation_rules: Vec<ValidationRule>

Built-in validation rules

base_type: Option<String>

Base type for type aliases (e.g., “String” for Email scalar)

Trait Implementations

impl Clone for IntermediateScalar

fn clone(&self) -> IntermediateScalar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntermediateScalar

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IntermediateScalar

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for IntermediateScalar

fn eq(&self, other: &IntermediateScalar) -> 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.

impl Serialize for IntermediateScalar

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
