Struct ContextId 

pub struct ContextId(/* private fields */);

Opaque identity of a DbmsContext.

The identity remains stable when the context is moved. It does not keep the context alive, so context-associated caches can discard stale entries.

Implementations

impl ContextId

pub fn is_alive(&self) -> bool

Returns whether the context that owns this identity still exists.

Trait Implementations

impl Clone for ContextId

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContextId

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

Formats the value using the given formatter.

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

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

Equality operator ==.

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

Inequality operator !=.
