Implementations

impl Model

pub fn display_name(&self) -> &'static str

Returns a human-readable display name for known models.

For Unknown models, callers should use derive_display_name with the raw model ID for a better fallback.

pub fn context_window_size(&self) -> u32

Returns the context window size for this model.

pub fn input_cost_per_million(&self) -> f64

Returns approximate cost per million input tokens (USD).

pub fn output_cost_per_million(&self) -> f64

Returns approximate cost per million output tokens (USD).

pub fn from_id(id: &str) -> Self

Parses a model from its string ID using prefix matching.

More specific prefixes are checked first to avoid false matches (e.g., “claude-sonnet-4-5” before “claude-sonnet-4-”).

pub fn is_unknown(&self) -> bool

Returns true if this is an unknown/unrecognized model.

Trait Implementations

impl Clone for Model

fn clone(&self) -> Model

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Model

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

Formats the value using the given formatter.

impl Default for Model

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Model

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Model

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

Formats the value using the given formatter.

impl Hash for Model

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 Model

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Model

impl Eq for Model

impl StructuralPartialEq for Model
