枚举 ReadExactError 

pub enum ReadExactError {
    FinishedEarly(usize),
    ReadError(ReadError),
}

从流读取时产生的错误。

变体

FinishedEarly(usize)

流在所有字节被读取完毕前已结束

ReadError(ReadError)

发生了读取错误

trait 实现

impl Clone for ReadExactError

fn clone(&self) -> ReadExactError

返回值的副本。 更多信息

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

Performs copy-assignment from source. 更多信息

impl Debug for ReadExactError

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

使用给定的格式化器格式化此值。 更多信息

impl Display for ReadExactError

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

使用给定的格式化器格式化此值。 更多信息

impl Error for ReadExactError

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

返回此错误的更底层来源（若有）。 更多信息

fn description(&self) -> &str

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

更多信息

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. 更多信息

impl From<ReadError> for ReadExactError

fn from(source: ReadError) -> Self

从输入类型转换为此类型。

impl PartialEq for ReadExactError

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

测试 self 与 other 值是否相等，供 == 运算符使用。

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
