Enum ChainResult 

pub enum ChainResult {
    Allow,
    ModifiedAllow(MemoryDelta),
    Deny {
        reason: String,
        code: i32,
    },
    AskUser {
        queued: Vec<AskUserPrompt>,
    },
}

What the chain runner reports back to the dispatcher. Mirrors HookDecision’s shape but at chain granularity:

• ChainResult::Allow — every hook in the chain returned Allow (or the chain was empty).
• ChainResult::ModifiedAllow — at least one hook returned Modify; the final merged delta is reported.
• ChainResult::Deny — a hook returned Deny (or a hook errored under FailMode::Closed); the chain short-circuited.
• ChainResult::AskUser — the chain finished with at least one queued operator prompt and no clear Allow / Modify win.

Modify is not a chain-level outcome on its own — every chain either also finishes Allow (ModifiedAllow) or short-circuits on Deny. The dispatcher applies the cumulative delta exactly once when the chain returns ModifiedAllow.

#969 — PartialEq is now derive-able because MemoryDelta derives PartialEq (see hooks/events.rs). Pre-#969 we hand-rolled equality routed through serde_json::to_value(...) on the (mistaken) premise that serde_json::Value was not PartialEq — it IS. MemoryDelta’s Option<f64> blocks derive(Eq) (f64 has only PartialEq) but not derive(PartialEq). The historical wrap-and-compare is gone.

Trait Implementations

impl Clone for ChainResult

fn clone(&self) -> ChainResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainResult

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

Formats the value using the given formatter.

impl PartialEq for ChainResult

fn eq(&self, other: &ChainResult) -> 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.
