Struct MissingMetadata 

pub struct MissingMetadata { /* private fields */ }

Missing metadata. This is only used if the compiler is configured to check for required metadata (see: crate::linters::Metadata).

Example

error[E038]: required metadata is missing
 --> test.yar:12:6
   |
12 | rule pants {
   |      ----- required metadata "date" not found
   |

Implementations

impl MissingMetadata

pub const fn code() -> &'static str

Returns a unique code identifying the type of error/warning.

Error codes have the form “Eddd”, where “ddd” is an error number (examples: “E001”, “E020”). Warnings have more descriptive codes, like: “slow_pattern”, “unsatisfiable_expr”, etc.

pub fn title(&self) -> &str

Returns the title of this error/warning.

pub fn labels(&self) -> impl Iterator<Item = Label<'_>>

Returns the labels associated to this error/warning.

pub fn footers(&self) -> impl Iterator<Item = Footer<'_>>

Returns the footers associated to this error/warning.

Trait Implementations

impl Clone for MissingMetadata

fn clone(&self) -> MissingMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MissingMetadata

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

Formats the value using the given formatter.

impl Display for MissingMetadata

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

Formats the value using the given formatter.

impl Error for MissingMetadata

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 MissingMetadata

fn eq(&self, other: &MissingMetadata) -> 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.

impl Serialize for MissingMetadata

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
