Enum HookAction 

pub enum HookAction {
    Continue(Box<HookContext>),
    Skip(Value),
    Abort {
        reason: String,
    },
    Replace(Value),
}

What the hook wants the runtime to do after execution.

Pre-hooks (can modify/abort)

• Continue — pass (possibly modified) context downstream
• Skip — skip the operation, return the given value as result
• Abort — abort the operation with an error

Post-hooks (observe/replace)

• Continue — pass context to next post-hook
• Replace — replace the result payload, continue chain

Intentional omission

Default is NOT implemented. Continue(HookContext::empty()) would destroy the original context silently. Handlers must return explicitly.

Variants

Continue(Box<HookContext>)

Continue with (possibly modified) context.

Skip(Value)

Skip the operation entirely (pre-hooks only). The Value is returned as the operation’s result.

Abort

Abort the operation with an error (pre-hooks only).

Fields

reason: String

Reason for aborting.

Replace(Value)

Replace the result with a different value (post-hooks only). In a post-hook chain, the replaced value becomes the new payload for subsequent hooks.

Implementations

Returns true if this is an Abort variant.

pub fn is_replace(&self) -> bool

Returns true if this is a Replace variant.
