pub fn new() -> Self

pub fn register(&self, type_name: &str, field_name: &str, resolver: ResolverFn)

注册解析器

key 格式为 “TypeName.fieldName”

pub fn get(&self, type_name: &str, field_name: &str) -> Option<Arc<ResolverFn>>

查找解析器

pub fn resolve( &self, type_name: &str, field_name: &str, parent: &Value, args: &HashMap<String, Value>, ) -> Option<Value>

解析字段

pub fn len(&self) -> usize

已注册的解析器数量

pub fn is_empty(&self) -> bool
