}

Kafka API key registry generated from the vendored schemas.

Each variant corresponds to a request/response pair defined in the schemas. Variants with validVersions = "none" are omitted (reserved keys with no currently-valid wire version).

The enum is #[non_exhaustive] so that adding variants for new Kafka API keys in future schema updates 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.

Implementations

impl ApiKey

pub const ALL: &'static [ApiKey]

All known API keys, in ascending numeric order.

pub fn from_i16(k: i16) -> Option<ApiKey>

Resolve from numeric key; returns None for unknown keys.

Trait Implementations

impl Clone for ApiKey

fn clone(&self) -> ApiKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ApiKey

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

Formats the value using the given formatter.

impl<'_derivative_strum> From<&'_derivative_strum ApiKey> for &'static str

fn from(x: &'_derivative_strum ApiKey) -> &'static str

Converts to this type from the input type.

impl From<ApiKey> for &'static str

fn from(x: ApiKey) -> &'static str

Converts to this type from the input type.

impl Hash for ApiKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ApiKey

fn eq(&self, other: &ApiKey) -> 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 Copy for ApiKey

impl Eq for ApiKey

impl StructuralPartialEq for ApiKey
