Enum ToolInvocationPhase 

pub enum ToolInvocationPhase {
    Setup,
    ParamHandling,
    Execution,
    ResultInterpretation,
}

Invocation phase in which a tool failure occurred, per arXiv:2601.16280.

Maps Zeph’s ToolErrorCategory variants to the 4-phase diagnostic framework: Setup → ParamHandling → Execution → ResultInterpretation.

Variants

Setup

Tool lookup/registration phase: was the tool name valid?

ParamHandling

Parameter validation phase: were the provided arguments well-formed?

Execution

Runtime execution phase: did the tool run successfully?

ResultInterpretation

Output parsing/interpretation phase: was the result usable? Reserved for future use — no current ToolErrorCategory maps here.

Implementations

impl ToolInvocationPhase

pub fn label(self) -> &'static str

Human-readable label for audit logs.

Trait Implementations

impl Clone for ToolInvocationPhase

fn clone(&self) -> ToolInvocationPhase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolInvocationPhase

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolInvocationPhase

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ToolInvocationPhase

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 ToolInvocationPhase

fn eq(&self, other: &ToolInvocationPhase) -> 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 ToolInvocationPhase

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
