Enum DecisionParseError 

pub enum DecisionParseError {
    NotAnObject,
    MissingAction,
    UnknownAction(String),
    MissingField {
        action: &'static str,
        field: &'static str,
    },
    Malformed(String),
}

Errors surfaced by HookDecision::parse. Hand-rolled Display + Error per the v0.7 lesson (no thiserror in this crate’s hot dependency tree).

Each variant is intentionally narrow so the executor’s warning log can name the failure mode (unknown action "foo" vs missing required field "reason").

Variants

NotAnObject

The payload was not a JSON object (e.g. an array or scalar).

MissingAction

The payload was a JSON object but had no action key. This is not the same as an empty {} — empty objects are treated as Allow per the wire contract. NotAnObject fires only when the bytes parse as JSON but action is missing on a non-empty object.

UnknownAction(String)

The action discriminator named a string we don’t recognise.

MissingField

The decision shape is recognised but a required field is missing (Deny without reason, Modify without delta, AskUser without prompt or options).

Fields

action: &'static str

field: &'static str

Malformed(String)

Underlying JSON syntax / type error from serde_json.

Trait Implementations

impl Debug for DecisionParseError

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

Formats the value using the given formatter.

impl Display for DecisionParseError

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

Formats the value using the given formatter.

impl Error for DecisionParseError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
