Why a DeclarativeProfile cannot be interpreted.

Every variant is a limit of the single-pass design rather than a passing problem with the input, so the same profile always fails the same way.

Variants

EmptyName

The profile has no name to put in a diagnostic.

NoCommentDelimiter

The profile declares neither a line nor a block comment.

EmptyDelimiter(&'static str)

The named token is the empty string, which would match everywhere.

AmbiguousDelimiter(String, String)

Two comment delimiters where one is a prefix of the other.

AmbiguousStringDelimiter(String, String)

Two string delimiters where one is a prefix of the other.

CommentStringCollision(String, String)

A comment delimiter and a string delimiter where one is a prefix of the other, so one position could open either.

InvalidNesting

A nested block whose start and end are equal or overlap, which no depth count can read.

NewlineDelimiter

A delimiter spanning a line terminator, which a one-line token cannot.

EmptyProtectedPattern

A ProtectedPattern with nothing to look for or no reason to give.

InvalidPolicyRegex(String)

A keep_regex or remove_regex entry of the ScanOptions would not compile.

Trait Implementations

impl Clone for ProfileError

fn clone(&self) -> ProfileError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProfileError

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

Formats the value using the given formatter.

impl Display for ProfileError

Formats the value using the given formatter.

impl Eq for ProfileError

impl Error for ProfileError

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 ProfileError

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

Equality operator ==.

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

Inequality operator !=.
