Enum SelectorError 

#[non_exhaustive]
pub enum SelectorError {
    Empty,
    EmptyFold,
    BadRegex(String),
    BadGlob(String),
}

Error type returned from ProcessSelector::parse

#[non_exhaustive]: only two of today’s four selector kinds have a failure mode of their own (fold: with no name, /regex/ that will not compile) — a future kind with its own malformed-value class, such as a status: filter rejecting a name that is not a known state, would need a new variant rather than stretching Self::BadRegex to mean something it does not, and shep-core is a published library an out-of-tree matcher should not break for (IR-20).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

The selector string was empty

EmptyFold

fold: with no fold name after the colon

BadRegex(String)

The /regex/ body failed to compile (carries the regex message)

BadGlob(String)

A glob pattern was rejected by globset (carries its message)

Trait Implementations

impl Eq for SelectorError

impl Error for SelectorError

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 PartialEq for SelectorError

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

Equality operator ==.

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

Inequality operator !=.
