Struct KeyId 

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

Process-wide handle identifier.

KeyId is a NonZeroU64 so that Option<KeyId> is the same size as KeyId itself (niche optimization), and so that 0 is unambiguously not a valid handle. Identifiers are allocated from a single process-global counter (crate-internal); they are unique within the lifetime of a process and not portable across runs.

Trait Implementations

impl Clone for KeyId

fn clone(&self) -> KeyId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyId

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

Formats the value using the given formatter.

impl Hash for KeyId

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 KeyId

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