Enum ParsePatternError 

pub enum ParsePatternError {
    InvalidRegex {
        pattern: Arc<str>,
        source: Error,
    },
    InvalidGlob {
        source: Error,
    },
}

普通模式解析错误

示例

use dhttp_access::pattern::{NormalPattern, ParsePatternError};

// 无效的正则表达式
let result: Result<NormalPattern, _> = "~ [".parse();
assert!(matches!(result, Err(ParsePatternError::InvalidRegex { .. })));

// 注意：大多数 glob 模式实际上是有效的，这里只是示例
// 实际的 InvalidGlob 错误比较难构造，通常发生在内部处理时

Variants

InvalidRegex

无效的正则表达式

Examples

use dhttp_access::pattern::{NormalPattern, ParsePatternError};

let result: Result<NormalPattern, _> = "~ [invalid".parse();
assert!(matches!(result, Err(ParsePatternError::InvalidRegex { .. })));

let result: Result<NormalPattern, _> = "~* (?P<invalid".parse();
assert!(matches!(result, Err(ParsePatternError::InvalidRegex { .. })));

Fields

pattern: Arc<str>

source: Error

InvalidGlob

无效的 Glob 模式

Examples

use dhttp_access::pattern::{NormalPattern, ParsePatternError};

// 注意：实际上多数 glob 模式是有效的，这里用简化的示例
let result = NormalPattern::new("***/invalid");
// 由于这个例子可能不会失败，我们使用 expect 来说明预期的错误类型
// assert!(matches!(result, Err(ParsePatternError::InvalidGlob { .. })));

Fields

source: Error

Trait Implementations

impl Clone for ParsePatternError

fn clone(&self) -> ParsePatternError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParsePatternError

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

Formats the value using the given formatter.

impl Display for ParsePatternError

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

Formats the value using the given formatter.

impl Error for ParsePatternError

where Self: Debug + Display,

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 ErrorCompat for ParsePatternError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
