Struct GlobalState 

pub struct GlobalState {
    pub type_id: StateTypeId,
    pub data: Vec<u8>,
}

Global state: contract-wide values visible to all parties

Examples: total supply, epoch number, configuration flags. Global state is not tied to any specific seal or owner.

Fields

type_id: StateTypeId

Type identifier (defined in the schema)

data: Vec<u8>

Serialized state data (schema-defined format)

Implementations

impl GlobalState

pub fn new(type_id: StateTypeId, data: Vec<u8>) -> Self

Create new global state

pub fn from_hash(type_id: StateTypeId, value: Hash) -> Self

Create global state from a single hash value

pub fn as_hash(&self) -> Option<Hash>

Get the state as a hash (convenience for 32-byte states)

Trait Implementations

impl Clone for GlobalState

fn clone(&self) -> GlobalState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GlobalState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GlobalState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for GlobalState

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 GlobalState

fn eq(&self, other: &GlobalState) -> 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 GlobalState

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for GlobalState
