pub struct ScalarMeta<'a, S> { /* private fields */ }

Expand description

Scalar type metadata

Implementations

source

impl<'a, S> ScalarMeta<'a, S> where
S: ScalarValue + 'a,

source

pub fn new<T>(name: Cow<'a, str>) -> Self where
T: FromInputValue<S> + ParseScalarValue<S> + 'a,

Build a new scalar type metadata with the specified name

source

pub fn description(self, description: &str) -> ScalarMeta<'a, S>

Set the description for the given scalar type

If a description already was set prior to calling this method, it will be overwritten.

source

pub fn into_meta(self) -> MetaType<'a, S>

Wrap the scalar in a generic meta type
