Struct fuel_tx::input::message::specifications::MessageData

pub struct MessageData<UsageRules>(_);

The retrayable message metadata. It is a message that can’t be used as a coin to pay for fees but can be used to pass metadata to the contract. It may have a non-zero value that will be transferred to the contract as a native asset during the execution. If the execution of the transaction fails, the metadata is not consumed and can be used later until successful execution.

Trait Implementations

impl<UsageRules: Clone> Clone for MessageData<UsageRules>

fn clone(&self) -> MessageData<UsageRules>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<UsageRules: Debug> Debug for MessageData<UsageRules>

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

Formats the value using the given formatter.

impl<UsageRules: Default> Default for MessageData<UsageRules>

fn default() -> MessageData<UsageRules>

Returns the “default value” for a type.

impl<UsageRules: Hash> Hash for MessageData<UsageRules>

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 MessageSpecification for MessageData<Predicate>

type Witness = ()

type Data = Vec<u8, Global>

type Predicate = Vec<u8, Global>

type PredicateData = Vec<u8, Global>

impl MessageSpecification for MessageData<Signed>

type Witness = u8

type Data = Vec<u8, Global>

type Predicate = ()

type PredicateData = ()

impl<UsageRules: PartialEq> PartialEq<MessageData<UsageRules>> for MessageData<UsageRules>

fn eq(&self, other: &MessageData<UsageRules>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
