Trait Implementations

impl Clone for ChooseNode

fn clone(&self) -> ChooseNode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChooseNode

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl RbatisAST for ChooseNode

fn eval(
    &self,
    convert: &impl StmtConvert,
    env: &mut Value,
    engine: &RbatisEngine,
    arg_array: &mut Vec<Value>
) -> Result<String, Error>

env: &mut Value,因为bind node 会绑定变量，env必须为可修改的值 arg_result: 执行后 提交到 驱动的参数

impl SqlNodePrint for ChooseNode

fn print(&self, deep: i32) -> String
