Struct TableScopedPath 

pub struct TableScopedPath {
    pub table: Option<TableReference>,
    pub path: Path,
}

Key for DefaultListFilesCache

Each entry is scoped to its use within a specific table so that the cache can differentiate between identical paths in different tables, and table-level cache invalidation.

Fields

table: Option<TableReference>

path: Path

Trait Implementations

impl CacheAccessor<TableScopedPath, CachedFileList> for DefaultListFilesCache

fn get(&self, key: &TableScopedPath) -> Option<CachedFileList>

Get a cached entry if it exists.

fn put( &self, key: &TableScopedPath, value: CachedFileList, ) -> Option<CachedFileList>

Store a value in the cache.

fn remove(&self, k: &TableScopedPath) -> Option<CachedFileList>

Remove an entry from the cache, returning the value if it existed.

fn contains_key(&self, k: &TableScopedPath) -> bool

Check if the cache contains a specific key.

fn len(&self) -> usize

Fetch the total number of cache entries.

fn clear(&self)

Remove all entries from the cache.

fn name(&self) -> String

Return the cache name.

fn is_empty(&self) -> bool

Check if the cache collection is empty.

impl Clone for TableScopedPath

fn clone(&self) -> TableScopedPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableScopedPath

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

Formats the value using the given formatter.

impl Hash for TableScopedPath

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 PartialEq for TableScopedPath

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