Enum StorageFormat 

pub enum StorageFormat {
    Auto,
    WalDirectory,
    SingleFile,
}

Storage format for persistent databases.

Controls whether the database uses a single .grafeo file or a legacy WAL directory. The default (Auto) auto-detects based on the path: files ending in .grafeo use single-file format, directories use WAL.

Variants

Auto

Auto-detect based on path: .grafeo extension = single file, existing directory = WAL directory, new path without extension = WAL directory.

WalDirectory

Legacy WAL directory format (directory with wal/ subdirectory).

SingleFile

Single .grafeo file with a sidecar .grafeo.wal/ directory during operation. At rest (after checkpoint), only the .grafeo file exists.

Trait Implementations

impl Clone for StorageFormat

fn clone(&self) -> StorageFormat

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StorageFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for StorageFormat

fn default() -> StorageFormat

Returns the “default value” for a type.

impl Display for StorageFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for StorageFormat

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StorageFormat

fn eq(&self, other: &StorageFormat) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
