Struct Capacity

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

CKB capacity.

It is encoded as the amount of Shannons internally.

Implementations

impl Capacity

pub const fn zero() -> Capacity

Capacity of zero Shannons.

pub const fn one() -> Capacity

Capacity of one Shannon.

pub const fn shannons(val: u64) -> Capacity

Views the capacity as Shannons.

pub fn bytes(val: usize) -> Result<Capacity, Error>

Views the capacity as CKBytes.

pub fn as_u64(self) -> u64

Views the capacity as Shannons.

pub fn safe_add<C>(self, rhs: C) -> Result<Capacity, Error>

where C: IntoCapacity,

Adds self and rhs and checks overflow error.

pub fn safe_sub<C>(self, rhs: C) -> Result<Capacity, Error>

where C: IntoCapacity,

Subtracts self and rhs and checks overflow error.

pub fn safe_mul<C>(self, rhs: C) -> Result<Capacity, Error>

where C: IntoCapacity,

Multiplies self and rhs and checks overflow error.

pub fn safe_mul_ratio(self, ratio: Ratio) -> Result<Capacity, Error>

Multiplies self with a ratio and checks overflow error.

Trait Implementations

impl Clone for Capacity

fn default() -> Capacity

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Capacity

fn deserialize<__D>( __deserializer: __D, ) -> Result<Capacity, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Capacity

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

Formats the value using the given formatter.

type Err = ParseIntError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Capacity, <Capacity as FromStr>::Err>

where __H: Hasher,

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 IntoCapacity for Capacity

fn into_capacity(self) -> Capacity

Converts self into Capacity.

impl LowerHex for Capacity

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

Formats the value using the given formatter.

impl Ord for Capacity

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

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

fn partial_cmp(&self, other: &Capacity) -> 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.

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 Serialize for Capacity

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
