Struct UnsignedInt

pub struct UnsignedInt(/* private fields */);

Variable Length Unsigned Integer. This provides more efficient serialization of 32-bit unsigned int. It serialuzes a 32-bit unsigned integer in as few bytes as possible. UnsignedInt is unsigned and uses VLQ or Base-128 encoding https://github.com/EOSIO/eosio.cdt/blob/4985359a30da1f883418b7133593f835927b8046/libraries/eosiolib/core/eosio/varint.hpp#L15-L237

Trait Implementations

fn from(v: UnsignedInt) -> Self

Converts to this type from the input type.

impl From<u16> for UnsignedInt

fn from(v: u16) -> Self

Converts to this type from the input type.

fn from(v: usize) -> Self

Converts to this type from the input type.

impl Hash for UnsignedInt

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 NumBytes for UnsignedInt

fn num_bytes(&self) -> usize

Count the number of bytes a type is expected to use.

impl Ord for UnsignedInt

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

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

fn partial_cmp(&self, other: &UnsignedInt) -> 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 Read for UnsignedInt

fn read(bytes: &[u8], pos: &mut usize) -> Result<Self, ReadError>

Read bytes.

fn unpack<T: AsRef<[u8]>>(bytes: T) -> Result<Self, ReadError>

Deserializes a byte array into a data type.

impl Write for UnsignedInt

fn write(&self, bytes: &mut [u8], pos: &mut usize) -> Result<(), WriteError>

Write bytes.

fn pack(&self) -> Result<Vec<u8>, WriteError>

Serializes data into a byte vector.
