Implementations

impl KeyFragment

pub fn integer(value: BigInt, bits: u16, signed: bool) -> Self

Create an integer key fragment

pub fn boolean(value: bool) -> Self

Create a boolean key fragment

pub fn address(bytes: impl Into<Vec<u8>>) -> Self

Create an address key fragment (20 bytes)

pub fn bytes(bytes: impl Into<Vec<u8>>) -> Self

Create a bytes key fragment

pub fn string(value: impl Into<String>) -> Self

Create a string key fragment

pub fn uint256(value: BigInt) -> Self

Create a uint256 key fragment

pub fn int256(value: BigInt) -> Self

Create an int256 key fragment

pub fn type_name(&self) -> &'static str

Get the type name of this fragment

Trait Implementations

impl Clone for KeyFragment

fn clone(&self) -> KeyFragment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyFragment

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

Formats the value using the given formatter.

impl PartialEq for KeyFragment

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