Struct NGraphBuilder 

pub struct NGraphBuilder<K: Key, T> { /* private fields */ }

图 构建器

Implementations

impl<K: Key, T> NGraphBuilder<K, T>

pub fn new() -> Self

创建 默认

pub fn new_with_graph(graph: NGraph<K, T>) -> Self

用已有的图 重新 构建

pub fn graph(&self) -> &NGraph<K, T>

pub fn has_node(&self, key: K) -> bool

对应节点是否存在

pub fn node(&mut self, key: K, value: T) -> &mut Self

添加 节点

pub fn edge(&mut self, from: K, to: K) -> &mut Self

添加 边

pub fn remove_node(&mut self, key: K) -> &mut Self

移除 节点

pub fn remove_edge(&mut self, from: K, to: K) -> &mut Self

移除 边

pub fn build(self) -> Result<NGraph<K, T>, Vec<K>>

构建图 返回Graph，或者 回环的节点
