Enum ParseError 

pub enum ParseError {
    IntError(ParseIntError),
    LengthError,
}

表示在解析操作期间可能发生的错误。

这个枚举包含两种变体:

• IntError: 在解析整数时发生错误。它包装了标准的ParseIntError，以提供更多上下文特定的错误信息。
• LengthError: 当拆分操作的长度出现问题时返回的错误，表示输入或输出不符合预期的长度要求。

Variants

IntError(ParseIntError)

LengthError

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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<ParseIntError> for ParseError

fn from(source: ParseIntError) -> Self

Converts to this type from the input type.
