Struct sanakirja::Statistics

pub struct Statistics {
    pub free_pages: HashSet<u64>,
    pub bookkeeping_pages: Vec<u64>,
    pub total_pages: usize,
    pub reference_counts: HashMap<u64, u64>,
}

Statistics about the database, useful for debugging and benchmarking purposes.

Fields

free_pages: HashSet<u64>

Set of free pages inside the file (not including the free space at the end of the file)

bookkeeping_pages: Vec<u64>

"Bookkeeping" pages, i.e. pages that contain just a list of free pages.

total_pages: usize

Total number of pages in the file that are either used or free. Does not include the free space at the end of the file.

reference_counts: HashMap<u64, u64>

A clone of the reference-counting structure, with an RC value for each page. Pages with an RC strictly less than 2 are not included.
