Enum FieldType 

pub enum FieldType {
    U8,
    U16,
    U32,
    U64,
    U128,
    I64,
    Bool,
    Bytes(usize),

Variants

U8

U16

U32

U64

U128

I64

Bool

Bytes(usize)

Fixed-length byte array.

Address

32-byte account/contract address.

Hash

32-byte hash (block hash, tx hash, etc).

Implementations

impl FieldType

pub fn fixed_size(&self) -> Option<usize>

Fixed encoded size in bytes. None if variable-length.

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

Trait Implementations

impl Clone for FieldType

fn clone(&self) -> FieldType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FieldType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FieldType

fn eq(&self, other: &FieldType) -> 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 Serialize for FieldType

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
