Struct tantivy::directory::RAMDirectory [−][src]
A Directory storing everything in anonymous memory.
It is mainly meant for unit testing. Writes are only made visible upon flushing.
Implementations
impl RAMDirectory
[src]
pub fn create() -> RAMDirectory
[src]
Constructor
pub fn total_mem_usage(&self) -> usize
[src]
Returns the sum of the size of the different files in the RAMDirectory.
pub fn persist(&self, dest: &dyn Directory) -> Result<()>
[src]
Write a copy of all of the files saved in the RAMDirectory in the target Directory
.
Files are all written using the Directory::write
meaning, even if they were
written using the atomic_write
api.
If an error is encounterred, files may be persisted partially.
