Struct 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 gstd::msg::id() function. Also, each send and reply functions return a message identifier.

Implementations

impl MessageId

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

Creates a new MessageId from a 32-byte array.

impl MessageId

pub const fn zero() -> Self

Creates a new zero MessageId.

pub fn is_zero(&self) -> bool

Checks whether MessageId is zero.

impl MessageId

pub fn into_bytes(self) -> [u8; 32]

Returns MessageIdas bytes array.

Trait Implementations

impl<__AsMutT: ?Sized> AsMut<__AsMutT> for MessageId

where [u8; 32]: AsMut<__AsMutT>,

fn as_mut(&mut self) -> &mut __AsMutT

Converts this type into a mutable reference of the (usually inferred) input type.

impl<__AsRefT: ?Sized> AsRef<__AsRefT> for MessageId

where [u8; 32]: AsRef<__AsRefT>,

fn as_ref(&self) -> &__AsRefT

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for MessageId

fn clone(&self) -> MessageId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MessageId

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

Formats the value using the given formatter.

impl Default for MessageId

fn default() -> MessageId

Returns the “default value” for a type.

impl Display for MessageId

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

Formats the value using the given formatter.

impl From<[u8; 32]> for MessageId

fn from(original: [u8; 32]) -> MessageId

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(original: MessageId) -> Self

Converts to this type from the input type.

impl From<MessageId> for H256

fn from(value: MessageId) -> Self

Converts to this type from the input type.

impl From<u64> for MessageId

fn from(value: u64) -> Self

Converts to this type from the input type.

impl FromStr for MessageId

type Err = ConversionError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

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,

Feeds a slice of this type into the given Hasher.

impl Ord for MessageId

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MessageId

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

fn partial_cmp(&self, other: &MessageId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
