Enum PoolError

#[non_exhaustive]
pub enum PoolError {
    Failed,
    Incomplete,
    Collision,
    CacheWriteFailed,
    CacheDamaged,
}

A metadata pool 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

Incomplete

The pool was loaded, but we had to ignore some metadata.

Collision

An AppStream-ID collision occured (a component with that ID already existed in the pool)

CacheWriteFailed

Unable to write to any cache file (not even tmpfs writes worked)

CacheDamaged

The disk cache was broken and we could not automatically recover.

Implementations

impl PoolError

pub fn quark() -> Quark

Trait Implementations

impl Clone for PoolError

fn clone(&self) -> PoolError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PoolError

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

Formats the value using the given formatter.

impl ErrorDomain for PoolError

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<PoolError> for Value

fn from(v: PoolError) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for PoolError

type Checker = GenericValueTypeChecker<PoolError>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for PoolError

type ParamSpec = ParamSpecEnum

type SetValue = PoolError

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for PoolError

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 PoolError

fn cmp(&self, other: &PoolError) -> 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 PoolError

fn eq(&self, other: &PoolError) -> 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 PoolError

fn partial_cmp(&self, other: &PoolError) -> 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 PoolError

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for PoolError

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 PoolError

type Type = PoolError

Type to get the Type from.

impl Copy for PoolError

impl Eq for PoolError
