Struct ScalarType

#[non_exhaustive]
pub struct ScalarType {
    pub name: String,
    pub description: Option<String>,
    pub specified_by_url: Option<String>,
}

Scalar types represent primitive leaf values in a GraphQL type system.

GraphQL provides a number of built-in scalars, however type systems may also add additional custom scalars to introduce additional semantic meaning.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

The name of the scalar

description: Option<String>

A description of the scalar

specified_by_url: Option<String>

A URL pointing to a specification for this scalar, if there is one

Implementations

impl ScalarType

pub fn is_builtin(&self) -> bool

Returns true if this scalar represents one of the built in scalars.

Trait Implementations

impl Clone for ScalarType

fn clone(&self) -> ScalarType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScalarType

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

Formats the value using the given formatter.

impl PartialEq for ScalarType

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