Enum HookEvent 

pub enum HookEvent {
    PreToolUse,
    PostToolUse,
    PostToolFailure,
    UserPromptSubmit,
    SessionStart,
    SessionEnd,
    Stop,
    SubAgentStart,
    PreCompact,
    PostCompact,
}

可拦截的 Agent 生命周期节点。

与 AgentEvent（28 种只读观察事件）互补，HookEvent 只覆盖 需要干预能力的节点 — 拦截、修改输入/输出、权限决策。

Examples

use katu_core::hook::HookEvent;

let event = HookEvent::PreToolUse;
assert!(event.is_tool_event());
assert!(!HookEvent::SessionStart.is_tool_event());

Variants

PreToolUse

工具执行前 — 可以 allow/deny/ask、修改 input。

PostToolUse

工具执行成功后 — 可以注入上下文、修改输出。

PostToolFailure

工具执行失败后 — 可以注入诊断上下文。

UserPromptSubmit

用户提交 prompt 前 — 可以注入上下文或拦截。

SessionStart

Session 开始。

SessionEnd

Session 结束。

Stop

Agent loop 单步结束判定 — 可以阻止停止、要求继续。

SubAgentStart

SubAgent 启动前。

PreCompact

上下文压缩前。

PostCompact

上下文压缩后。

Implementations

impl HookEvent

pub fn is_tool_event(&self) -> bool

是否为 Tool 相关事件。

Trait Implementations

impl Clone for HookEvent

fn clone(&self) -> HookEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HookEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HookEvent

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for HookEvent

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

Formats the value using the given formatter.

impl Hash for HookEvent

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HookEvent

fn eq(&self, other: &HookEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for HookEvent

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for HookEvent

impl Eq for HookEvent

impl StructuralPartialEq for HookEvent
