Struct OwnedIconCache 

pub struct OwnedIconCache {
    pub lock: FileLock,
    pub memmap: Mmap,
}

Provides access to an IconCache constructed from a file that is guaranteed not to be modified.

OwnedIconCache holds a lock on the cache file and creates a memory-mapped region with the file’s contents inside. It does not copy the file contents.

To access the icon cache, use OwnedIconCache::icon_cache

Fields

Implementations

impl OwnedIconCache

pub fn open(path: impl AsRef<Path>) -> Result<Self>

Open and lock a file. This call may block waiting to acquire a lock if an exclusive lock is already held.

If this behaviour is undesirable, use open_non_blocking instead.

pub fn open_non_blocking(path: impl AsRef<Path>) -> Result<Self>

Open and lock a file, returning an error if an exclusive lock on the file was already held by another process.

pub fn icon_cache<'a>(&'a self) -> Result<IconCache<'a>, Box<dyn Error + 'a>>

Access the icon cache held by this OwnedIconCache.

Returns an error if the cache could not be parsed.

pub fn from_lock(lock: FileLock) -> Result<Self>

Create a OwnedIconCache from a locked file
