Execution context.

Contains information that is useful on most invocations as it is always included without requiring any explicit queries.

Fields

instance_id: InstanceId

Contract instance identifier.

instance_address: Address

Contract instance address.

caller_address: Address

Caller address.

deposited_tokens: Vec<BaseUnits>

Tokens deposited by the caller.

read_only: bool

Read-only flag.

A read-only call cannot make any changes to runtime state. Any attempt at modifying state will result in the call failing.

call_format: CallFormat

Transaction’s call format.

Trait Implementations

impl Debug for ExecutionContext

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

Formats the value using the given formatter.

impl Decode for ExecutionContext

fn try_default() -> Result<Self, DecodeError>

Try to decode from a missing/null/undefined value.

fn try_from_cbor_value(value: Value) -> Result<Self, DecodeError>

Try to decode from a given CBOR value.

fn try_from_cbor_value_default(value: Value) -> Result<Self, DecodeError>

where Self: Sized,

Try to decode from a given CBOR value, calling try_default in case the value is null or undefined.

impl Default for ExecutionContext

fn default() -> ExecutionContext

Returns the “default value” for a type.

impl Encode for ExecutionContext

fn into_cbor_value(self) -> Value

Encode the type into a CBOR Value.

fn is_empty(&self) -> bool

Whether the value is equal to the empty value for the type.

impl EncodeAsMap for ExecutionContext

fn into_cbor_value_map(self) -> Value

where Self: Sized,

Encode the type into a CBOR Map.

fn into_cbor_map(self) -> Vec<(Value, Value)>

where Self: Sized,

Encode the type into a CBOR Map, returning the map items.
