Canonical Anthropic beta header values.

This list is derived from the public API reference and may grow over time. New values added by the API will deserialize into Self::Other until this enum is updated.

Implementations

impl BetaHeader

pub fn as_str(&self) -> &str

Wire-format string sent in the anthropic-beta HTTP header.

pub fn is_known(&self) -> bool

Whether this is a recognized known variant (not Self::Other).

Trait Implementations

impl Clone for BetaHeader

fn clone(&self) -> BetaHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BetaHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BetaHeader

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for BetaHeader

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

Formats the value using the given formatter.

impl From<&BetaHeader> for String

fn from(b: &BetaHeader) -> Self

Converts to this type from the input type.

impl From<&str> for BetaHeader

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<BetaHeader> for String

fn from(b: BetaHeader) -> Self

Converts to this type from the input type.

impl From<String> for BetaHeader

fn from(s: String) -> Self

Converts to this type from the input type.

impl Hash for BetaHeader

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 BetaHeader

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

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Eq for BetaHeader

impl StructuralPartialEq for BetaHeader
