Struct EventType 

pub struct EventType { /* private fields */ }

A validated event type name.

Invariants: valid UTF-8, length ≤ MAX_EVENT_TYPE_LEN.

Backed by Bytes; constructible from a &'static str literal at zero allocation via from_static_str, or from arbitrary Bytes via the validating from_bytes.

Implementations

impl EventType

pub fn from_static_str(s: &'static str) -> Self

Construct from a &'static str literal. Infallible for valid literals: &str is UTF-8 by Rust’s type system, and program-text literals are bounded by the source file.

Panics

Panics if s.len() > MAX_EVENT_TYPE_LEN. For string literals this is a programmer error caught at first use; the runtime check catches the Box::leak(String::from(runtime)) case that would otherwise silently corrupt the wire encoding.

pub fn from_bytes(bytes: Bytes) -> Result<Self, ValueError>

Construct from arbitrary bytes, validating UTF-8 and size cap.

Errors

• ValueError::EventTypeTooLong if bytes.len() > MAX_EVENT_TYPE_LEN.
• ValueError::EventTypeInvalidUtf8 if bytes is not valid UTF-8.

pub fn as_str(&self) -> &str

Borrow as &str. Zero-cost; UTF-8 is guaranteed by construction.

pub fn as_bytes(&self) -> &[u8]

Borrow as &[u8].

pub fn into_bytes(self) -> Bytes

Take ownership of the inner Bytes (one Arc share, no copy).
