Struct SessionVersion 

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

Account-wide generation; revocation must fail on overflow rather than reuse a version.

Implementations

impl SessionVersion

pub const fn new(value: u64) -> Self

Wraps a nonnegative product generation value.

pub const fn value(self) -> u64

Returns the generation for product persistence.

pub fn next(self) -> Result<Self>

Advances without saturating or wrapping.

Errors

Returns InvalidPolicy when the generation is exhausted.

Trait Implementations

impl Clone for SessionVersion

fn clone(&self) -> SessionVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionVersion

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SessionVersion

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SessionVersion

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 SessionVersion

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

impl Serialize for SessionVersion

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
