Enum LogEvent 

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

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.

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 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 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.
