Struct HookContext 

pub struct HookContext {
    pub tenant_id: Option<i64>,
    pub operator_id: Option<i64>,
    pub timestamp: u64,
    pub metadata: HashMap<String, String>,
}

钩子执行上下文

携带请求级别的元数据，供钩子读取/修改。

Fields

tenant_id: Option<i64>

当前租户 ID（多租户场景）

operator_id: Option<i64>

当前操作人 ID

timestamp: u64

时间戳（Unix 微秒）

metadata: HashMap<String, String>

额外元数据

Implementations

impl HookContext

pub fn new() -> HookContext

创建新的空上下文

设置租户 ID

pub fn with_operator(self, operator_id: i64) -> HookContext

设置操作人 ID

pub fn with_timestamp(self, ts: u64) -> HookContext

设置时间戳

pub fn set_meta(&mut self, key: impl Into<String>, value: impl Into<String>)

插入元数据

pub fn get_meta(&self, key: &str) -> Option<&String>

读取元数据

Trait Implementations

impl Clone for HookContext

fn clone(&self) -> HookContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HookContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for HookContext

fn default() -> HookContext

Returns the “default value” for a type.

impl HookContextExt for HookContext

fn with_meta( self, key: impl Into<String>, value: impl Into<String>, ) -> HookContext
