Struct boa::environment::declarative_environment_record::DeclarativeEnvironmentRecordBinding

pub struct DeclarativeEnvironmentRecordBinding {
    pub value: Option<JsValue>,
    pub can_delete: bool,
    pub mutable: bool,
    pub strict: bool,
}

Declarative Bindings have a few properties for book keeping purposes, such as mutability (const vs let). Can it be deleted? and strict mode.

So we need to create a struct to hold these values. From this point onwards, a binding is referring to one of these structures.

Fields

value: Option<JsValue>

can_delete: bool

mutable: bool

strict: bool
