Every way a Kopitiam Runtime operation can fail.

This is one shared error type across the runtime crates rather than a per-crate error enum. Inference is a single pipeline — a shape mismatch deep in a kernel surfaces to the caller who asked for a token — and threading five From conversions through every layer to express that buys nothing but ceremony.

Note what is not here: no Other(String) escape hatch. Every variant carries the structured data needed to explain the failure, because “InvalidModel: something went wrong” is exactly the kind of error that costs an afternoon to debug.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Error

Converts to this type from the input type.

impl From<Error> for ConstrainedGenerateError

fn from(e: Error) -> Self

Converts to this type from the input type.
