Enum Value

pub enum Value {
    Bool(bool),
    Int(i64),
    Str(Rc<str>),
    List(SliceRef<Value>),
    Dict(Rc<NameIDMap<Value>>),

}

Expand description

A value represented during compilation of a Papyri source file.

Variants§

Bool(bool)

A Boolean value, either True or False.

Int(i64)

A 64-bit signed integer value.

Str(Rc<str>)

A string value.

List(SliceRef<Value>)

A list of values.

Dict(Rc<NameIDMap<Value>>)

A dictionary of values. The dictionary keys are strings, and must be valid identifiers not beginning with underscores.

HTML(HTML)

Some HTML content, represented as a value. HTML text content is instead represented as Value::Str.

Func(Func)

A function, either defined in a Papyri source file, or with a native implementation.

Regex(Rc<RegexValue>)

A regular expression.

Implementations§

impl Value

pub fn get_type(&self) -> Type
