Enum UpgradePolicy 

#[repr(u8)]
pub enum UpgradePolicy {
    Compatible = 0,
    Additive = 128,
    DepOnly = 192,
}

Rust representation of upgrade policy constants in iota::package.

Variants

Compatible = 0

The least restrictive policy. Permits changes to all function implementations, the removal of ability constraints on generic type parameters in function signatures, and modifications to private, public(friend), and entry function signatures. However, public function signatures and existing types cannot be changed.

Additive = 128

Allows adding new functionalities (e.g., new public functions or structs) but restricts changes to existing functionalities.

DepOnly = 192

Limits modifications to the package’s dependencies only.

Implementations

impl UpgradePolicy

pub const ADDITIVE: u8 = 128u8

pub const DEP_ONLY: u8 = 192u8

pub fn is_valid_policy(policy: &u8) -> bool

Trait Implementations

impl Clone for UpgradePolicy

fn clone(&self) -> UpgradePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UpgradePolicy

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

Formats the value using the given formatter.

impl Display for UpgradePolicy

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

Formats the value using the given formatter.

impl PartialEq for UpgradePolicy

fn eq(&self, other: &UpgradePolicy) -> 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 TryFrom<u8> for UpgradePolicy

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.
