Enum ScanError 

pub enum ScanError {
    InferenceFailed {
        reason: String,
    },
    EmptyInput,
}

scan_text 错误类型。Stage 1 scaffold 主要覆盖 EmptyInput; InferenceFailed 为 ISS-008 真模型接入预留 variant,现阶段不会由本函数返出。

Variants

InferenceFailed

未来真模型(onnxruntime / Transformers.js via native host)推理失败时返此。 caller 应视为 fail-closed:不要降级为“空 findings = 安全“。

Fields

reason: String

失败原因(模型名 / backend / errno 等);不应含用户原文内容。

EmptyInput

空输入约定:scaffold 对空输入返 Err 而非空 OK,避免 caller 误以为“已扫并安全“。 调用点应该在上游用 if input.is_empty() { .. } 明确决策分支。

Trait Implementations

impl Debug for ScanError

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

Formats the value using the given formatter.

impl Display for ScanError

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

Formats the value using the given formatter.

impl Error for ScanError

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.
