Enum CrdtScalar 

pub enum CrdtScalar {
    Int(i64),
    Text(String),
    Bool(bool),
}

A scalar CRDT element. CRDT collections are homogeneous, so a collection only ever holds one of these variants in practice; the enum exists because the interpreter is dynamically typed and the element type is not threaded through struct_defs.

Variants

Int(i64)

Text(String)

Bool(bool)

Implementations

impl CrdtScalar

pub fn from_runtime(value: &RuntimeValue) -> Result<CrdtScalar, String>

Project a RuntimeValue onto a CRDT element. Only the scalar types the surface syntax can put in a shared collection are accepted; anything else is a type error at the seam (never a silent coercion).

pub fn to_runtime(&self) -> RuntimeValue

Reconstitute a RuntimeValue from a CRDT element.

pub fn render(&self) -> String

The canonical Show rendering of an element — matches how the compiled tier prints the same scalar.

Trait Implementations

impl Clone for CrdtScalar

fn clone(&self) -> CrdtScalar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CrdtScalar

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CrdtScalar

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for CrdtScalar

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 Ord for CrdtScalar

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

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

fn partial_cmp(&self, other: &CrdtScalar) -> 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 Serialize for CrdtScalar

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
