Enum LmError 

pub enum LmError {
    Engine(String),
    ProviderStream(String),
    InvalidToolArguments(String),
    ToolArgumentsNotObject,
    IncompleteToolCall,
    MissingToolCallId,
    ToolCallSerialization(String),
}

Why a LanguageModel call failed.

Provider-neutral: an adapter maps its engine’s native error into one of these kinds, so no provider-specific error type reaches the public interface.

Variants

Engine(String)

The generation engine itself failed — an inference error, a worker that crashed, a model that never loaded. Carries a human-readable description.

ProviderStream(String)

The provider stream failed mid-generation.

InvalidToolArguments(String)

A tool call’s arguments were structurally invalid.

ToolArgumentsNotObject

Tool-call arguments were not a JSON object.

IncompleteToolCall

A provider tool call was incomplete — missing its name or arguments.

MissingToolCallId

A provider tool call carried no identifier.

ToolCallSerialization(String)

Serializing validated tool arguments to JSON text failed.

Trait Implementations

impl Clone for LmError

fn clone(&self) -> LmError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LmError

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

Formats the value using the given formatter.

impl Display for LmError

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

Formats the value using the given formatter.

impl Eq for LmError

impl Error for LmError

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<LmError> for StageError

fn from(e: LmError) -> Self

Converts to this type from the input type.

impl PartialEq for LmError

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

Equality operator ==.

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

Inequality operator !=.
