Find

Enum Find 

Source
pub enum Find {
    Regex(Regex),
    Fn(fn(&mut State<'_>) -> bool),
}
Expand description

匹配查找器。

封装了底层的匹配引擎,支持正则表达式或自定义的 Rust 闭包。

Variants§

§

Regex(Regex)

基于 regex::Regex 的正则匹配。

§

Fn(fn(&mut State<'_>) -> bool)

自定义状态处理闭包,修改 State 并返回是否匹配成功。

Implementations§

Source§

impl Find

Source

pub fn find(&self, state: &mut State<'_>) -> bool

在给定的状态中执行查找,过滤并保留命中的范围。

Source

pub fn is_match(&self, input: &str) -> bool

检查给定的字符串是否满足匹配条件(不保留命中范围,仅作布尔判断)。
