Struct ModelId 

pub struct ModelId(/* private fields */);

Identifier for a Claude model.

Stored as a string rather than an enum so a new model release does not require an SDK bump. Common models are exposed as associated constants for ergonomics; arbitrary values can be constructed with ModelId::custom.

use claude_api::types::ModelId;

let known = ModelId::SONNET_4_6;
let custom = ModelId::custom("claude-some-future-model");
assert_eq!(known.as_str(), "claude-sonnet-4-6");
assert_eq!(custom.as_str(), "claude-some-future-model");

Implementations

impl ModelId

pub const OPUS_4_7: ModelId

Borrow the underlying string.

Trait Implementations

impl AsRef<str> for ModelId

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ModelId

fn clone(&self) -> ModelId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModelId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ModelId

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

Deserialize this value from the given Serde deserializer.

impl Display for ModelId

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

Formats the value using the given formatter.

impl From<&'static str> for ModelId

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

Converts to this type from the input type.

impl From<ModelId> for AgentModel

Available on crate feature managed-agents-preview only.

fn from(m: ModelId) -> Self

Converts to this type from the input type.

impl From<String> for ModelId

fn from(s: String) -> Self

Converts to this type from the input type.

impl Hash for ModelId

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 ModelId

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

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

Serialize this value into the given Serde serializer.

impl Eq for ModelId

impl StructuralPartialEq for ModelId
