Struct Struct 

pub struct Struct { /* private fields */ }

Represents a Struct value.

Structs are cheap to clone.

Implementations

impl Struct

pub fn new<S, V>( context: Option<&dyn EvaluationContext>, ty: impl Into<Type>, members: impl IntoIterator<Item = (S, V)>, ) -> Result<Self>

where S: Into<String>, V: Into<Value>,

Creates a new struct value.

Returns an error if the struct type does not contain a member of a given name or if a value does not coerce to the corresponding member’s type.

Panics

Panics if the given type is not a struct type.

pub fn ty(&self) -> Type

Gets the type of the Struct value.

pub fn name(&self) -> &Arc<String>

Gets the name of the struct.

pub fn iter(&self) -> impl ExactSizeIterator<Item = (&str, &Value)>

Iterates the members of the struct.

pub fn keys(&self) -> impl ExactSizeIterator<Item = &str>

Iterates the keys of the struct.

pub fn values(&self) -> impl ExactSizeIterator<Item = &Value>

Iterates the values of the struct.

pub fn contains_key(&self, key: &str) -> bool

Determines if the struct contains the given member name.

pub fn get(&self, key: &str) -> Option<&Value>

Gets a value from the struct by member name.
