impl FileCacheEntry
pub fn uri(&self) -> Arc<str>
sourcepub fn try_open_assume_latest(&self) -> PolarsResult<File>
pub fn try_open_assume_latest(&self) -> PolarsResult<File>
Directly returns the cached file if it finds one without checking if there is a newer version on the remote. This does not make any API calls if it finds a cached file, otherwise it simply downloads the file.
sourcepub fn try_open_check_latest(&self) -> PolarsResult<File>
pub fn try_open_check_latest(&self) -> PolarsResult<File>
Returns the cached file after ensuring it is up to date against the remote This will always perform at least 1 API call for fetching metadata.
