[−][src]Struct juniper::meta::Argument
Metadata for an argument to a field
Implementations
impl<'a, S> Argument<'a, S>
[src]
pub fn is_builtin(&self) -> bool
[src]
Returns true if the type is built-in to GraphQL.
impl<'a, S> Argument<'a, S>
[src]
pub fn description(mut self: Self, description: &str) -> Self
[src]
Set the description of the argument
This overwrites the description if any was previously set.
pub fn default_value(mut self: Self, default_value: InputValue<S>) -> Self
[src]
Set the default value of the argument
This overwrites the default value if any was previously set.
