Struct Atom 

pub struct Atom {
    pub value: TrackedMutex<Value>,
    pub meta: TrackedMutex<Option<Value>>,
    pub validator: TrackedMutex<Option<Value>>,
    pub watches: TrackedMutex<Vec<(Value, Value)>>,
}

A Clojure atom — a thread-safe mutable reference.

Fields

value: TrackedMutex<Value>

meta: TrackedMutex<Option<Value>>

validator: TrackedMutex<Option<Value>>

watches: TrackedMutex<Vec<(Value, Value)>>

Implementations

impl Atom

pub fn new(v: Value) -> Self

pub fn snapshot(&self) -> ValueSnapshot

pub fn deref(&self) -> Value

pub fn reset(&self, v: Value) -> Value

pub fn compare_and_set(&self, expected: &Value, value: Value) -> bool

Replace the value only if it still equals expected. Failed attempts do not publish or lease the candidate.

pub fn add_watch(&self, key: Value, callback: Value)

pub fn remove_watch(&self, key: &Value)

pub fn protect_watches(&self)

pub fn get_meta(&self) -> Option<Value>

pub fn set_meta(&self, m: Option<Value>)

pub fn get_validator(&self) -> Option<Value>

pub fn set_validator(&self, vf: Option<Value>)

Trait Implementations

impl Debug for Atom

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

Formats the value using the given formatter.

impl Trace for Atom

fn trace(&self, visitor: &mut MarkVisitor)
