Enum MetadataError

#[non_exhaustive]
pub enum MetadataError {
    Failed,
    Parse,
    FormatUnexpected,
    NoComponent,
    ValueMissing,
}

A metadata processing error.

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.

Failed

Generic failure.

Parse

Unable to parse the metadata file.

FormatUnexpected

Expected catalog metadata but got metainfo metadata, or vice versa.

NoComponent

We expected a component in the pool, but couldn’t find one.

ValueMissing

A essential value is missing in the source document.

Implementations

impl MetadataError

pub fn quark() -> Quark

Trait Implementations

impl Clone for MetadataError

fn clone(&self) -> MetadataError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataError

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

Formats the value using the given formatter.

impl ErrorDomain for MetadataError

fn domain() -> Quark

Returns the quark identifying the error domain.

fn code(self) -> i32

Gets the integer representation of the variant.

fn from(code: i32) -> Option<Self>

Tries to convert an integer code to an enum variant.

impl From<MetadataError> for Value

fn from(v: MetadataError) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for MetadataError

type Checker = GenericValueTypeChecker<MetadataError>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for MetadataError

type ParamSpec = ParamSpecEnum

type SetValue = MetadataError

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: MetadataError) -> ParamSpecEnumBuilder<'_, MetadataError>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for MetadataError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for MetadataError

fn cmp(&self, other: &MetadataError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MetadataError

fn eq(&self, other: &MetadataError) -> 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 PartialOrd for MetadataError

fn partial_cmp(&self, other: &MetadataError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for MetadataError

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for MetadataError

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for MetadataError

type Type = MetadataError

Type to get the Type from.

impl Copy for MetadataError

impl Eq for MetadataError
