Struct gstd::MessageId

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

Message identifier.

Gear allows users and program interactions via messages. Each message has its own unique 256-bit id. This id is represented via the MessageId struct. The message identifier can be obtained for the currently processed message using the msg::id function. Also, each send and reply functions return a message identifier.

Implementations

impl MessageId

pub const fn new(arr: [u8; 32]) -> Self

Calculates the encoded size.

impl From<[u8; 32]> for MessageId

fn from(arr: [u8; 32]) -> Self

Converts to this type from the input type.

impl From<H256> for MessageId

fn from(h256: H256) -> Self

Converts to this type from the input type.

impl From<MessageId> for [u8; 32]

fn from(other: MessageId) -> Self

Converts to this type from the input type.

impl From<MessageId> for MessageId

fn from(other: MessageId) -> Self

impl Hash for MessageId

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,

impl Ord for MessageId

fn cmp(&self, other: &MessageId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

impl PartialEq<MessageId> for MessageId

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