Implementations

impl GeminiModel

pub fn as_api_id(&self) -> &str

Returns the full API model identifier.

pub fn as_cli_name(&self) -> &str

Returns the CLI shorthand name.

Trait Implementations

impl Clone for GeminiModel

fn clone(&self) -> GeminiModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeminiModel

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

Formats the value using the given formatter.

impl Default for GeminiModel

fn default() -> Self

Returns the “default value” for a type.

impl Display for GeminiModel

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

Formats the value using the given formatter.

impl Eq for GeminiModel

impl From<GeminiModel> for Model

fn from(m: GeminiModel) -> Self

Converts to this type from the input type.

impl FromStr for GeminiModel

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 GeminiModel

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 GeminiModel

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