Enum LogEvent 

#[non_exhaustive]
pub enum LogEvent {
    SessionStart,
    CapabilityResolved,
    Resolve,
    Fetch,
    StoreWrite,
    SessionEnd,
    RepeatForced,
}

Event class for a log row (PROVENANCE_LOG.md §3).

Note: result-status (ok/err/denied) lives in LogResult, NOT in the event variant. So Fetch covers both successful and failed fetch attempts; the row’s result distinguishes them.

non_exhaustive so adding new variants is non-breaking.

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.

SessionStart

Process started; first row of a new session.

CapabilityResolved

Capability resolution finished (allowed / denied / which env var).

Resolve

Reference resolved to a fetch URL.

Fetch

Fetch attempt (success or failure determined by result).

StoreWrite

Store write attempt (success or failure determined by result).

SessionEnd

Process ended cleanly.

RepeatForced

A caller asked again, with force, about a ref this session had already been answered on – a request repeat suppression would otherwise have replayed (#507, ADR-0057). The row is the record that the override was used.

Trait Implementations

impl Clone for LogEvent

fn clone(&self) -> LogEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LogEvent

impl Debug for LogEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LogEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for LogEvent

impl PartialEq for LogEvent

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
