Enum SharedThumbnailLookup 

#[non_exhaustive]
pub enum SharedThumbnailLookup<T> {
    FullyVerified(T),
    MetadataIncomplete(T),
    Missing,
    Invalid(Vec<CacheEntryProblem>),
    Unverifiable(Vec<CacheEntryProblem>),
}

Result of a validated shared thumbnail repository lookup.

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.

FullyVerified(T)

The cache entry exists and required metadata and PNG constraints are fully verified.

MetadataIncomplete(T)

The cache entry is otherwise usable but lacks standard-optional shared freshness metadata.

Missing

The computed shared cache path does not exist.

Invalid(Vec<CacheEntryProblem>)

The cache entry exists but is invalid for the requested context.

Unverifiable(Vec<CacheEntryProblem>)

Caller-supplied shared original facts are insufficient to verify the entry.

Trait Implementations

impl<T: Clone> Clone for SharedThumbnailLookup<T>

fn clone(&self) -> SharedThumbnailLookup<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for SharedThumbnailLookup<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for SharedThumbnailLookup<T>

fn eq(&self, other: &SharedThumbnailLookup<T>) -> 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.
