Enum Error 

pub enum Error {
    Ffi(String),
    NullHandle(String),
    Json(Error),
    Nul(NulError),
    NonUtf8Path(PathBuf),
    Other(String),
}

audio-cpp 高层 API 的错误类型。

Variants

Ffi(String)

C ABI 调用失败（返回非 0），msg 为 shim 的 audiocpp_last_error()。

NullHandle(String)

C++ 侧返回空句柄（如加载模型 / 创建会话失败），msg 为错误信息。

Json(Error)

JSON 解析 / 序列化错误。

Nul(NulError)

字符串或路径中含 NUL 字节，无法转为 C 字符串。

NonUtf8Path(PathBuf)

路径含非法 UTF-8（capi.h 约定所有字符串均为 UTF-8）。

Other(String)

其他运行时错误（如示例中用户自选解码库的失败信息）。

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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) -> Self

Converts to this type from the input type.

impl From<NulError> for Error

fn from(source: NulError) -> Self

Converts to this type from the input type.
