Enum ShimError 

pub enum ShimError {
    Nul(NulError),
    InvalidArg,
    BadJson(String),
    Failed(String),
    Init(String),
    Utf8(FromUtf8Error),
    CorruptResult,
}

The error type every shim-backed module shares.

chat::ChatError, ngram::NgramError, common_sampler::CommonSamplerError and runtime::RuntimeError are all aliases of this one type: the C shims share a status enum and a thread-local error buffer, so they share an error. Re-exported here because those aliases are public API and their variants should be documented somewhere reachable. A failure inside one of llama.cpp’s C++ layers, reported through a shim.

One type for every shim-backed module. The variants are the union of what the shims can report; a given call only produces the ones its documentation names.

Variants

Nul(NulError)

An argument contained an interior NUL byte, so it could not become a CString. Caught in Rust — truncating at the NUL would silently change the value.

InvalidArg

A required pointer argument was null, or a value was out of range.

BadJson(String)

Input was not valid JSON.

Failed(String)

llama.cpp threw. The message is what the exception carried.

Init(String)

A constructor returned null.

Utf8(FromUtf8Error)

Output was not valid UTF-8.

CorruptResult

A shim reported an offset outside the buffer it described, which would mean the shim and this crate disagree about the layout.

Trait Implementations

impl Debug for ShimError

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

Formats the value using the given formatter.

impl Display for ShimError

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

Formats the value using the given formatter.

impl Error for ShimError

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<FromUtf8Error> for ShimError

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.

impl From<NulError> for ShimError

fn from(source: NulError) -> Self

Converts to this type from the input type.
