Struct SignatureTopicArg

pub struct SignatureTopicArg { /* private fields */ }

The signature topic argument of an event variant.

Used as part of ink::event macro.

Implementations

impl SignatureTopicArg

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

Trait Implementations

impl Clone for SignatureTopicArg

fn clone(&self) -> SignatureTopicArg

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureTopicArg

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

Formats the value using the given formatter.

impl From<&[u8; 32]> for SignatureTopicArg

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

Converts to this type from the input type.

impl Hash for SignatureTopicArg

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 SignatureTopicArg

fn cmp(&self, other: &SignatureTopicArg) -> 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 SignatureTopicArg

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

fn partial_cmp(&self, other: &SignatureTopicArg) -> 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.

impl TryFrom<&Lit> for SignatureTopicArg

type Error = Error

The type returned in the event of a conversion error.

fn try_from(lit: &Lit) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&MetaNameValue> for SignatureTopicArg

type Error = Error

The type returned in the event of a conversion error.

fn try_from(nv: &MetaNameValue) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&MetaValue> for SignatureTopicArg

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &MetaValue) -> Result<Self, Self::Error>

Performs the conversion.
