Enum UnaccountedReason 

pub enum UnaccountedReason {
    MediaType,
    Unparseable,
    TaskIdMismatch,
    Oversized,
}

Why a response the edge observed produced no accounting at all.

Four unrelated causes shared one counter, so an operator watching mcp_usage_unrecognized_responses_total climb could tell that responses were going unaccounted and nothing about why. They need opposite responses: a media type means the origin is misconfigured and revenue is being lost, a capture overflow means the capture bound is set too low for this traffic, and a task-id mismatch means the origin answered the wrong question.

Variants

MediaType

The origin declared a media type the meter does not read as MCP.

Unparseable

The body was read but was not a JSON-RPC response.

TaskIdMismatch

A tasks/get was answered with a different task than it asked for.

Oversized

The captured body exceeded the configured capture bound, so the terminal result was never seen.

Implementations

impl UnaccountedReason

pub const ALL: [Self; 4]

Every reason, in a stable order.

Callers index metric slots by position, so appending is safe and reordering is not.

pub const fn as_str(self) -> &'static str

The stable wire name, written out so renaming a variant cannot silently change what an operator’s dashboard is keyed on.

pub const fn index(self) -> usize

Position in Self::ALL, and so in the metric slots.
