Struct HookEntry 

pub struct HookEntry {
    pub name: String,
    pub point: HookPoint,
    pub callback_id: String,
}

A named hook registration that will be attached to an agent.

The callback_id is an opaque identifier used to look up the actual Rust callback in the hook runner. This decouples serialization from function pointers.

Construction

Prefer HookEntry::new which validates eagerly. Direct struct construction is allowed for deserialization but skips validation — call HookEntry::validate before use if constructing manually.

Fields

name: String

Descriptive name (e.g. "safety_gate").

point: HookPoint

Which lifecycle point this hook fires at.

callback_id: String

Opaque callback identifier for the hook runner to resolve.

Implementations

impl HookEntry

pub fn new( name: impl Into<String>, point: HookPoint, callback_id: impl Into<String>, ) -> Result<Self, Error>

Create a new hook entry, validating that name and callback_id are non-empty.

Errors

Returns Error::InvalidConfig if name or callback_id is empty or whitespace-only.

Examples

let entry = HookEntry::new("safety_gate", HookPoint::PreToolCallDecide, "cb_safety")
    .expect("valid entry");
assert_eq!(entry.name, "safety_gate");

pub fn validate(&self) -> Result<(), Error>

Validate that the entry has non-empty name and callback_id.

Errors

Returns Err with a description if the name or callback_id is empty.
