Variants

Address

Address.

Bytes

Bytes.

Int(usize)

Signed integer.

Uint(usize)

Unsigned integer.

Bool

Boolean.

String

String.

Array(Box<ParamKind>)

Array of unknown size.

FixedBytes(usize)

Vector of bytes with fixed size.

FixedArray(Box<ParamKind>, usize)

Array with fixed size.

Tuple(Vec<Box<ParamKind>>)

Tuple containing different types

Implementations

impl ParamKind

pub fn is_empty_bytes_valid_encoding(&self) -> bool

returns whether a zero length byte slice (0x) is a valid encoded form of this param type

pub fn is_dynamic(&self) -> bool

returns whether a ParamKind is dynamic used to decide how the ParamKind should be encoded

Trait Implementations

impl Clone for ParamKind

fn clone(&self) -> ParamKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamKind

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

Formats the value using the given formatter.

impl PartialEq for ParamKind

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