Expand description
A variable definition inside a list of variable definitions, for example $name:String!
.
Fields
name: Positioned<Name>
The name of the variable, without the preceding $
.
var_type: Positioned<Type>
The type of the variable.
directives: Vec<Positioned<Directive>>
The variable’s directives.
default_value: Option<Positioned<ConstValue>>
The optional default value of the variable.
Implementations
sourceimpl VariableDefinition
impl VariableDefinition
sourcepub fn default_value(&self) -> Option<&ConstValue>
pub fn default_value(&self) -> Option<&ConstValue>
Get the default value of the variable; this is default_value
if it is present,
Value::Null
if it is nullable and None
otherwise.
