[−]Struct ejdb::open_mode::DatabaseOpenMode
Several bit flags defining how an EJDB database should be opened.
This type has Default
implementation which returns the most common set of open
mode flags:
assert_eq!( DatabaseOpenMode::default(), DatabaseOpenMode::READ | DatabaseOpenMode::WRITE | DatabaseOpenMode::CREATE );
This default set of flags is used by Database::open()
static method.
Methods
impl DatabaseOpenMode
impl DatabaseOpenMode
pub const READ: DatabaseOpenMode
Open the database in read-only mode.
pub const WRITE: DatabaseOpenMode
Open the database in write-only mode.
pub const CREATE: DatabaseOpenMode
Create the database file if it does not exist.
pub const TRUNCATE: DatabaseOpenMode
Truncate the database after opening it.
pub const NO_LOCK: DatabaseOpenMode
Open the database without locking.
pub const LOCK_WITHOUT_BLOCKING: DatabaseOpenMode
Lock the database without blocking.
pub const SYNC: DatabaseOpenMode
Synchronize every transaction.
pub fn empty() -> DatabaseOpenMode |
Returns an empty set of flags.
pub fn all() -> DatabaseOpenMode |
Returns the set containing all flags.
pub fn bits(&self) -> u32 |
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: u32) -> Option<DatabaseOpenMode> |
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub fn from_bits_truncate(bits: u32) -> DatabaseOpenMode |
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub fn is_empty(&self) -> bool |
Returns true
if no flags are currently stored.
pub fn is_all(&self) -> bool |
Returns true
if all flags are currently set.
pub fn intersects(&self, other: DatabaseOpenMode) -> bool |
Returns true
if there are flags common to both self
and other
.
pub fn contains(&self, other: DatabaseOpenMode) -> bool |
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: DatabaseOpenMode) |
Inserts the specified flags in-place.
pub fn remove(&mut self, other: DatabaseOpenMode) |
Removes the specified flags in-place.
pub fn toggle(&mut self, other: DatabaseOpenMode) |
Toggles the specified flags in-place.
pub fn set(&mut self, other: DatabaseOpenMode, value: bool) |
Inserts or removes the specified flags depending on the passed value.
impl DatabaseOpenMode
[src]
impl DatabaseOpenMode
pub fn open<P: Into<Vec<u8>>>(self, path: P) -> Result<Database> | [src] |
Invokes Database::open_with_mode()
with this mode and the provided path as arguments.
This is a convenient shortcut for creating database with non-default options.
Example
let db = (DatabaseOpenMode::default() | DatabaseOpenMode::TRUNCATE).open("path/to/db"); // equivalent to let db = Database::open_with_mode( "path/to/db", DatabaseOpenMode::default() | DatabaseOpenMode::TRUNCATE );
