Enum Value

Variants

Nil

Bool(bool)

Number(Fraction)

String(String)

Symbol(String)

Bytes(Vec<u8>)

Pair(Box<Pair>)

Vector(Vec<Value>)

Closure(Closure)

Struct

Fields

name: String

fields: Vec<Value>

Commodity

Commodity-bearing amount: rational value tagged with the originating commodity entity id. Distinct from Number so the type system refuses cross-strata arithmetic (Commodity + Ratio, Commodity + Commodity with different commodity_ids) at compile or runtime. Conversion between commodities goes through the Prices table via (convert-commodity ...).

Fields

amount: Fraction

commodity_id: Uuid

Implementations

impl Value

pub fn is_truthy(&self) -> bool

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

pub fn as_bytes(&self) -> Option<&[u8]>

pub fn from_bytes(b: impl Into<Vec<u8>>) -> Self

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl PartialEq for Value

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