Trait Implementations

impl Default for GoManager

fn default() -> Self

Returns the “default value” for a type.

impl VersionManager for GoManager

fn install<'life0, 'async_trait>( &'life0 self, request: InstallRequest, ) -> Pin<Box<dyn Future<Output = Result<VersionInfo, String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

fn switch_to(&self, request: SwitchRequest) -> Result<(), String>

切换到指定版本

fn uninstall(&self, request: UninstallRequest) -> Result<(), String>

卸载指定版本

fn list_installed( &self, request: ListInstalledRequest, ) -> Result<VersionList, String>

列出已安装的版本

扫描基础目录中的所有子目录，返回包含有效Go安装的版本目录列表。 自动排除：
