Enum ClaudeModel 

pub enum ClaudeModel {
    Opus45,
    Sonnet45,
    Opus41,
    Opus4,
    Sonnet4,
    Haiku35,
    Custom(String),
}

Anthropic Claude model identifiers.

Examples

use llm_toolkit::models::ClaudeModel;

// Use predefined models
let model = ClaudeModel::Opus45;
assert_eq!(model.as_api_id(), "claude-opus-4-5-20251124");

// Parse from string (shorthand or full name)
let model: ClaudeModel = "opus".parse().unwrap();
assert_eq!(model, ClaudeModel::Opus45);

// Custom model (validated)
let model: ClaudeModel = "claude-future-model-2026".parse().unwrap();

Implementations

impl ClaudeModel

pub fn as_api_id(&self) -> &str

Returns the full API model identifier.

Use this when making API calls to Anthropic.

pub fn as_cli_name(&self) -> &str

Returns the CLI shorthand name.

Use this when invoking CLI tools like claude.

Trait Implementations

impl Clone for ClaudeModel

fn clone(&self) -> ClaudeModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClaudeModel

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

Formats the value using the given formatter.

impl Default for ClaudeModel

fn default() -> Self

Returns the “default value” for a type.

impl Display for ClaudeModel

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

Formats the value using the given formatter.

impl From<ClaudeModel> for Model

fn from(m: ClaudeModel) -> Self

Converts to this type from the input type.

impl FromStr for ClaudeModel

type Err = ModelError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ClaudeModel

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 ClaudeModel

fn eq(&self, other: &ClaudeModel) -> 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.
