Struct redb::DatabaseBuilder

pub struct DatabaseBuilder { /* private fields */ }

Implementations

impl DatabaseBuilder

pub fn new() -> Self

pub fn set_page_size(&mut self, size: usize) -> &mut Self

Set the internal page size of the database Larger page sizes will reduce the database file’s overhead, but may decrease write performance Defaults to the native OS page size

pub fn set_region_size(&mut self, size: usize) -> &mut Self

Set the internal region size of the database Smaller regions may allow the database to compact more effectively, but will limit the maximum size of values that can be stored Defaults to 4GiB

pub fn set_dynamic_growth(&mut self, enabled: bool) -> &mut Self

Whether to grow the database file dynamically. When set to true, the database file will start at a small size and grow as insertions are made When set to false, the database file will be statically sized

pub unsafe fn create(
    &self,
    path: impl AsRef<Path>,
    db_size: usize
) -> Result<Database, Error>

Opens the specified file as a redb database.

• if the file does not exist, or is an empty file, a new database will be initialized in it
• if the file is a valid redb database, it will be opened
• otherwise this function will return an error

db_size: the maximum size in bytes of the database.

Safety

The file referenced by path must not be concurrently modified by any other process
