Implementations

impl EventName

pub fn parse(s: &str) -> Result<EventName, ParseEventNameError>

The parsed string is EventName.

pub fn try_from_event_str(s: &str) -> Result<EventName, ParseEventNameError>

Parses an event string into an EventName with explicit error handling.

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

Returns a string representation of the event type.

pub fn expand(&self) -> Vec<EventName>

Returns the extended value of the abbreviation event type.

pub fn mask(&self) -> u64

Returns the mask of type. The compound “All” type will be expanded.

Bit budget

A leaf event’s mask is 1 << (discriminant - 1), so the enum can hold at most 64 variants in total — compound “All” variants included, because they consume discriminants even though they own no bit of their own and so push every later leaf further up the range.

The last variant is currently KmsServiceStopped at discriminant LAST_EVENT_NAME_VALUE, leaving 64 - LAST_EVENT_NAME_VALUE free slots. Before adding an event, check that number; if the budget is gone, widen the mask beyond u64 rather than reusing a bit.

Three guards back this up: the const assertion next to LAST_EVENT_NAME_VALUE fails the build once that discriminant passes 64; test_event_name_discriminants_are_dense_and_fully_listed fails if the anchor is left stale or a variant goes unlisted; and test_every_event_mask_is_nonzero_and_leaf_bits_are_unique fails on the bit collision a wrapped shift produces in release builds.

pub fn is_removed(&self) -> bool

Returns true for every object-removal event variant.

Covers all ObjectRemoved* leaf events, including the internal (metrics-only) ones, so callers can categorize removals without enumerating each variant by hand.

pub fn is_kms(&self) -> bool

Returns true for KMS management-plane events.

These are audit-only: they are never emitted through the bucket notification pipeline, and no s3: event selector expands to them.

pub fn is_iam(&self) -> bool

Whether this is an IAM identity management-plane event.

Mirrors Self::is_kms: these reach the audit sink only, so nothing in the bucket notification path should ever select them.
