Enum AppError 

pub enum AppError {
    FfmpegNotFound,
    FfmpegFailed {
        code: Option<i32>,
        stderr: String,
    },
    Io(Error),
    Whisper(WhisperError),
    Audio(String),
    InvalidPath(PathBuf),
    Other(String),
}

流水线各阶段可能产生的错误。

Variants

FfmpegNotFound

系统 PATH 中未找到 ffmpeg，且未通过 CLI --ffmpeg 指定有效路径。

FfmpegFailed

FFmpeg 子进程以非零状态退出。

Fields

code: Option<i32>

进程退出码；被信号终止时可能为 None。

stderr: String

FFmpeg 标准错误输出（已去除首尾空白）。

Io(Error)

文件读写等标准库 IO 错误。

Whisper(WhisperError)

whisper-rs / whisper.cpp 推理或模型加载失败。

Audio(String)

WAV 格式不符合要求，或样本读取失败。

InvalidPath(PathBuf)

输入视频、模型路径等不存在或不可作为 UTF-8 路径使用。

Other(String)

其它未分类错误（预留扩展）。

Trait Implementations

impl Debug for AppError

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

Formats the value using the given formatter.

impl Display for AppError

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

Formats the value using the given formatter.

impl Error for AppError

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 AppError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<WhisperError> for AppError

fn from(source: WhisperError) -> Self

Converts to this type from the input type.
