pub struct ScopeRegistry { /* private fields */ }Expand description
全局作用域注册表
管理多个 GlobalScope 的启用/禁用状态。
典型用法:临时禁用软删除作用域以查询已删除行(without_scope)。
Implementations§
Source§impl ScopeRegistry
impl ScopeRegistry
Sourcepub fn new() -> ScopeRegistry
pub fn new() -> ScopeRegistry
创建空注册表(所有作用域默认启用)
Sourcepub fn is_enabled(&self, scope_name: &str) -> bool
pub fn is_enabled(&self, scope_name: &str) -> bool
检查作用域是否启用
Sourcepub fn without_scope<F, R>(&self, scope_name: &str, f: F) -> Rwhere
F: FnOnce() -> R,
pub fn without_scope<F, R>(&self, scope_name: &str, f: F) -> Rwhere
F: FnOnce() -> R,
在闭包内临时禁用作用域
let registry = ScopeRegistry::new();
registry.without_scope("soft_delete", || {
// 此处查询会包含已软删除的行
