trait 实现

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value. 阅读更多

fn clone_from(&mut self, source: &Self)

从 source 执行拷贝赋值。 阅读更多

impl Debug for Error

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

使用给定的格式化器格式化该值。 阅读更多

impl Display for Error

使用给定的格式化器格式化该值。 阅读更多

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any. 阅读更多

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

阅读更多

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. 阅读更多

impl From<Error> for Error

fn from(value: Error) -> Error

Converts to this type from the input type.

impl From<Error> for c_int

fn from(value: Error) -> c_int

Converts to this type from the input type.

impl From<i32> for Error

fn from(value: c_int) -> Error

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

测试 !=。默认实现几乎总是足够的，没有充分理由不应被重写。
