Struct UnsupportedFeatureError

pub struct UnsupportedFeatureError { /* private fields */ }

Error raised when rsonpath is asked to perform an operation that is currently unsupported. This may be either because the feature is in the works, or because it is not planned to ever be supported.

Implementations

impl UnsupportedFeatureError

pub fn large_json_depths() -> Self

Large JSON Depths feature – supporting JSON documents with nesting depth exceeding 255. Unsupported and not planned.

pub fn large_automaton_queries() -> Self

Large Automaton Queries feature – supporting queries that cause compiled DFAs to exceed 256 states. Unsupported and not planned.

pub fn multiple_selectors() -> Self

Multiple Selector per Segment feature – supporting queries that contain a union of selectors per step. Unsupported and not planned (yet).

pub fn indexing_from_end() -> Self

Indexing from End – supporting index and slice selectors that use from-end indexing. Unsupported and not planned (yet).

pub fn slice_selector() -> Self

Slice Selector – supporting slice selectors. https://github.com/V0ldek/rsonpath/issues/152

pub fn slice_with_backward_step() -> Self

Slice with Backward Step – supporting slice selectors that step backwards. Unsupported and not planned (yet).

pub fn filter_selector() -> Self

Filter Selector – supporting filter selectors. https://github.com/V0ldek/rsonpath/issues/154

pub fn issue(&self) -> Option<usize>

Returns the issue number on GitHub corresponding to the unsupported feature. Is None if the feature is not planned.

pub fn feature(&self) -> &str

Returns the descriptive name of the feature.

pub fn is_planned(&self) -> bool

Whether the issue is planned to ever be supported.

Trait Implementations

impl Debug for UnsupportedFeatureError

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

Formats the value using the given formatter.

impl Display for UnsupportedFeatureError

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

Formats the value using the given formatter.

impl Error for UnsupportedFeatureError

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
