Struct dust_lang::Map

pub struct Map { /* private fields */ }

A collection dust variables comprised of key-value pairs.

The inner value is a BTreeMap in order to allow VariableMap instances to be sorted and compared to one another.

Implementations

impl Map

pub fn new() -> Self

Creates a new instace.

pub fn clone_from(other: &Self) -> Result<Self>

pub fn variables( &self ) -> Result<RwLockReadGuard<'_, BTreeMap<String, (Value, Type)>>>

pub fn variables_mut( &self ) -> Result<RwLockWriteGuard<'_, BTreeMap<String, (Value, Type)>>>

pub fn set( &self, key: String, value: Value, type: Option<Type> ) -> Result<Option<(Value, Type)>>

pub fn unset_all(&self) -> Result<()>

pub fn clear(&self) -> Result<()>

Trait Implementations

impl Clone for Map

fn clone(&self) -> Map

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Map

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

Formats the value using the given formatter.

impl Default for Map

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Map

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Map

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

Formats the value using the given formatter.

impl Ord for Map

fn cmp(&self, other: &Self) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Map

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Map

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Map

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
