Enum CapabilityError 

pub enum CapabilityError {
    ModalityUnsupported {
        model: String,
        kind: MediaKind,
    },
    SourceKindUnsupported {
        model: String,
        kind: MediaKind,
        attempted: SourceKind,
        accepted: EnumSet<SourceKind>,
    },

        kind: MediaKind,
        format: String,
        accepted: Vec<&'static str>,
    },
    SizeExceeded {
        model: String,
        kind: MediaKind,
        bytes: u64,

    },
}

Reasons a request can fail capability validation, by precision.

Returned from LanguageModelProvider::validate_request and surfaced both at the application boundary (predict / direct generate) and at the application configuration preflight (where the same validation runs against the declared schema rather than the actual values).

Variants

ModalityUnsupported

The model has no MediaSupport entry for this modality at all.

Fields

model: String

kind: MediaKind

SourceKindUnsupported

The model accepts this modality but not via this source kind. accepted enumerates what would work. The field is named attempted (rather than source) so thiserror doesn’t try to treat it as an Error::source() provider — it’s a discriminant, not a chained error.

Fields

model: String

kind: MediaKind

attempted: SourceKind

accepted: EnumSet<SourceKind>

FormatUnsupported

The model accepts this modality + source but not this MIME subtype (e.g. JPEG image submitted to a model that only takes PNG).

Fields

model: String

kind: MediaKind

format: String

accepted: Vec<&'static str>

SizeExceeded

InlineBytes payload exceeds the model’s declared cap.

Fields

model: String

kind: MediaKind

bytes: u64

max: u64

UnknownModel

The capability table has no entry for model at all — the model is either too new (unmodeled) or misspelled. Surfaced when a non-text content part is sent against an unknown model. Pure text calls do not produce this; they bypass capability lookup.

Fields

model: String

kind: MediaKind

Trait Implementations

impl Clone for CapabilityError

fn clone(&self) -> CapabilityError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CapabilityError

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

Formats the value using the given formatter.

impl Display for CapabilityError

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

Formats the value using the given formatter.

impl Eq for CapabilityError

impl Error for CapabilityError

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 PartialEq for CapabilityError

fn eq(&self, other: &CapabilityError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
