pub enum DbInstanceKey {
    File(Arc<str>),
    Memory,
}

A key that uniquely identifies a database instance.

Variants

File(Arc<str>)

Implementations

impl DbInstanceKey

pub fn memory() -> Self

pub fn file(path: Arc<str>) -> Self

Trait Implementations

impl Clone for DbInstanceKey

fn clone(&self) -> DbInstanceKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DbInstanceKey

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

Formats the value using the given formatter.

impl Hash for DbInstanceKey

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 DbInstanceKey

fn eq(&self, other: &DbInstanceKey) -> 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.
