Enum EngineError 

pub enum EngineError {
    ModelNotFound {
        dir: String,
    },
    TokenizerLoad(String),
    SessionInit(String),
    InferRun(String),
    DecodeShape(String),
    Internal(String),
}

引擎私有诊断错误。

6 变体覆盖从模型加载到张量解码的全链路失败模式;绝不持有 ort::Error 本身(rc.12 该类型非 Send + Sync,会污染 trait object 边界)。所有 ort/tokenizer 错误一律 e.to_string() 后塞进 String 字段。

caller 拿到的不是这个类型 —— From<EngineError> for ScanError 把 6 变体 全塌缩到 ScanError::InferenceFailed,只暴露统一的 reason。

Variants

ModelNotFound

指定 dir 下缺少模型文件(tokenizer.json / config.json / model_q4f16.onnx 三件齐全才算就绪)或 VIGIL_PRIVACY_FILTER_MODEL_DIR 未设置。

Fields

dir: String

失败时尝试加载的目录(诊断用,不含模型权重内容)

TokenizerLoad(String)

tokenizers::Tokenizer::from_file 失败。内部串来自 tokenizers crate。

SessionInit(String)

ORT Session::builder / commit_from_file / 优化等级设置等 init 阶段失败。

InferRun(String)

推理执行阶段失败(tokenizer.encode / session.run)。

DecodeShape(String)

输出张量 shape 不符预期或 try_extract_tensor::<f32> 失败。

Internal(String)

其它内部错误(config.json 解析 / Mutex poisoned 等),用兜底变体避免新增 variant 立刻冲击 caller。

Trait Implementations

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

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<EngineError> for ScanError

fn from(e: EngineError) -> Self

Converts to this type from the input type.
