Enum UsageData 

#[non_exhaustive]
pub enum UsageData {
    Endpoint(EndpointUsage),
    Jsonl(JsonlUsage),
}

What DataContext::usage surfaces after the cascade in docs/specs/data-fetching.md §OAuth fallback cascade finishes. The variant IS the provenance tag per ADR-0013: segments dispatch on it to pick between percent rendering (endpoint) and raw-token rendering (JSONL). #[non_exhaustive] leaves room for a future third source without a SemVer break.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Endpoint(EndpointUsage)

Jsonl(JsonlUsage)

Trait Implementations

impl Clone for UsageData

fn clone(&self) -> UsageData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UsageData

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

Formats the value using the given formatter.

impl PartialEq for UsageData

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