Struct dust_lang::Identifier

pub struct Identifier(/* private fields */);

A string by which a variable is known to a context.

Every variable is a key-value pair. An identifier holds the key part of that pair. Its inner value can be used to retrieve a Value instance from a Map.

Implementations

impl Identifier

pub fn new(inner: String) -> Self

pub fn take_inner(self) -> String

pub fn inner(&self) -> &String

Trait Implementations

impl AbstractTree for Identifier

fn from_syntax_node( source: &str, node: Node<'_>, _context: &Map ) -> Result<Self>

Interpret the syntax tree at the given node and return the abstraction.

fn run(&self, _source: &str, context: &Map) -> Result<Value>

Execute dust code by traversing the tree.

fn expected_type(&self, context: &Map) -> Result<Type>

impl Clone for Identifier

fn clone(&self) -> Identifier

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Identifier

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Identifier

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for Identifier

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

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

fn partial_cmp(&self, other: &Identifier) -> 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 Identifier

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
