示例

use dhttp_access::pattern::{LocationPattern, ParseLocationPatternError};

// 未知符号
let result: Result<LocationPattern, _> = "@ /invalid".parse();
assert!(matches!(result, Err(ParseLocationPatternError::UnknownSymbol { .. })));

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

// 未定义的前缀或通用模式
let result: Result<LocationPattern, _> = "invalid".parse();
assert!(matches!(result, Err(ParseLocationPatternError::UndefinedPrefixOrCommon { .. })));

Trait Implementations

impl Clone for ParseLocationPatternError

fn clone(&self) -> ParseLocationPatternError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseLocationPatternError

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

Formats the value using the given formatter.

impl Display for ParseLocationPatternError

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

Formats the value using the given formatter.

impl Error for ParseLocationPatternError

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 ParseLocationPatternError

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.
