pub struct Argument<'a, S> { /* private fields */ }
Expand description
Metadata for an argument to a field
Implementations
sourceimpl<'a, S> Argument<'a, S>
impl<'a, S> Argument<'a, S>
sourcepub fn is_builtin(&self) -> bool
pub fn is_builtin(&self) -> bool
Returns true if the type is built-in to GraphQL.
sourceimpl<'a, S> Argument<'a, S>
impl<'a, S> Argument<'a, S>
sourcepub fn description(self, description: &str) -> Self
pub fn description(self, description: &str) -> Self
Set the description of the argument
This overwrites the description if any was previously set.
sourcepub fn default_value(self, default_value: InputValue<S>) -> Self
pub fn default_value(self, default_value: InputValue<S>) -> Self
Set the default value of the argument
This overwrites the default value if any was previously set.
