Enum ParamType 

pub enum ParamType {
    Address,
    Uint(usize),
    Int(usize),
    Bool,
    Bytes,
    FixedBytes(usize),
    String,
    Array(Box<ParamType>),
    FixedArray(Box<ParamType>, usize),
    Tuple(Vec<(Option<String>, ParamType)>),
}

ABI parameter types — recursive to support tuples and arrays.

Variants

Address

Uint(usize)

Int(usize)

Bool

Bytes

FixedBytes(usize)

String

Array(Box<ParamType>)

FixedArray(Box<ParamType>, usize)

Tuple(Vec<(Option<String>, ParamType)>)

Implementations

impl ParamType

pub fn is_dynamic(&self) -> bool

Whether this type is dynamically-sized in ABI encoding.

pub fn head_size(&self) -> usize

Number of bytes this type occupies in the ABI head section.

Dynamic types always take 32 bytes (an offset pointer). Static types take 32 bytes for atomic types, or the sum of member head sizes for static tuples and fixed arrays of static elements.

Trait Implementations

impl Clone for ParamType

fn clone(&self) -> ParamType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamType

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

Formats the value using the given formatter.

impl PartialEq for ParamType

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