Struct I64

pub struct I64 {
    pub negative: bool,
    pub magnitude: u64,
}

As Move does not support negative numbers natively, we use our own internal representation.

To consume these values, first call get_is_negative() to determine if the I64 represents a negative or positive value. Then call get_magnitude_if_positive() or get_magnitude_if_negative() to get the magnitude of the number in unsigned u64 format. This API forces consumers to handle positive and negative numbers safely.

Fields

negative: bool

magnitude: u64

Implementations

impl I64

fn clone(&self) -> I64

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for I64

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for I64

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for I64

impl MoveStruct for I64

type StructTag = I64TypeTag

impl MoveType for I64

type TypeTag = I64TypeTag

fn from_bcs(bytes: &[u8]) -> Result<Self, Error>

Deserialize the contents of the Move type from BCS bytes.

fn into_bcs(self) -> Result<Vec<u8>, Error>
