Enum ConnectError 

#[non_exhaustive]
pub enum ConnectError {
    Malformed {
        reference: String,
    },
    CatalogOnly {
        vendor: String,
        served_by: &'static str,
    },
    NotFound(NotFound),
    Selection(SelectionError),
    MissingKey {
        vendor: String,
        tried: Vec<Cow<'static, str>>,
    },
    Provider(String),
    Env(EnvError),
    NoHttpClient,
}

Why Catalog::connect built no model.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Malformed

The reference is not vendor/model.

Fields

reference: String

What was given.

CatalogOnly

The provider is one only the catalog knows; its companion crate serves its models.

Fields

vendor: String

The provider’s vendor name.

served_by: &'static str

Where its models are served from.

NotFound(NotFound)

The reference names a vendor this build does not know. Its suggestions are close references the catalog lists.

Selection(SelectionError)

The vendor is not registered for the family asked for.

MissingKey

No key was given and none of these variables is set to a non-empty value.

Fields

vendor: String

The vendor.

tried: Vec<Cow<'static, str>>

The variables read, in order: built-in names, or names a provider reads at run time.

Provider(String)

The provider serving the model failed, in its own words, such as a Provide whose gateway is not configured.

Env(EnvError)

A variable the dialect reads is set but unusable.

NoHttpClient

No HTTP client was given, and this build has no shared one (the reqwest feature is off).

Trait Implementations

impl Debug for ConnectError

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

Formats the value using the given formatter.

impl Display for ConnectError

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

Formats the value using the given formatter.

impl Error for ConnectError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<EnvError> for ConnectError

fn from(source: EnvError) -> Self

Converts to this type from the input type.

impl From<NotFound> for ConnectError

fn from(source: NotFound) -> Self

Converts to this type from the input type.

impl From<SelectionError> for ConnectError

fn from(source: SelectionError) -> Self
