Errors for filter parser module

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.

Io(IOError)

Proxy value for std::io::Error

Network(HttpClientError)

Proxy value for http client errors

EmptyIf

Token !#if has no condition expression after that

UnbalancedElse

At least one !#else directive is redundant, because it is not balanced with the !#if directive.

UnbalancedEndIf

At least one !#endif directive is redundant, because it is not balanced with the !#if directive.

UnbalancedIf

We’ve found unbalanced if/else/endif expressions after compiling the filter

RecursiveInclusion

Recursive filter inclusion detected

StackIsCorrupted

Stack is corrupted. This is internal error

SchemeIsIncorrect(String)

Scheme problems marker

InvalidBooleanExpression

Expression passed into !#endif is invalid

InvalidChecksum(String, String)

Calculated invalid checksum

NoContent

Next patch is not compiled yet. So the remote file is empty

FilterContentIsLikelyNotAFilter

When filter’s body is not valid filters body by parser’s heuristics

Other(String)

Other errors

Trait Implementations

impl Debug for FilterParserError

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

Formats the value using the given formatter.

impl Display for FilterParserError

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

Formats the value using the given formatter.

impl Error for FilterParserError

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 FilterParserError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
