Enum StrError 

pub enum StrError {
    CapacityExceeded(BytesError),
    InvalidUtf8(Utf8Error),
    NullPointer,
}

Available on crate features types-str and types only.

安全字符串的错误类型。

Feature Requirement

需要启用 "types-str" 特性。

Examples

use core::convert::TryInto;
use lib_unknown::types::str::{StackStr, StrError};

let res: Result<StackStr<2>, _> = "toolong".try_into();
assert!(matches!(res, Err(StrError::CapacityExceeded(_))));

Variants

CapacityExceeded(BytesError)

长度超出容器容量。

InvalidUtf8(Utf8Error)

源内容不是合法 UTF-8（源仍会被清零）。

NullPointer

收到空指针。

Trait Implementations

impl Debug for StrError

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

Formats the value using the given formatter.

impl Display for StrError

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

Formats the value using the given formatter.

impl Error for StrError

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.
