Enum IconRequest 

pub enum IconRequest {
    Path(String),
    Url(String),
    Extension(String),
    Data(String),
}

图标请求类型，表示不同来源的图标提取需求。 各类型使用各自的提取逻辑完成图标提取。

Variants

Path(String)

本地文件路径 (exe, lnk, url, ico, png) -> 提取文件图标

Url(String)

网址 -> 下载或查找本地域名图标库

Extension(String)

文件扩展名 (.txt, .doc) -> 获取系统关联图标

Data(String)

已编码的图标数据（data URL 或 base64）-> 解码直通，不做文件/网络提取

Implementations

impl IconRequest

pub fn value(&self) -> &str
