Enum IntegrityLevel 

pub enum IntegrityLevel {
    Sealed,
    Frozen,
}

Object integrity level.

Variants

Sealed

Sealed object integrity level.

Preventing new properties from being added to it and marking all existing properties as non-configurable. Values of present properties can still be changed as long as they are writable.

Frozen

Frozen object integrity level

A frozen object can no longer be changed; freezing an object prevents new properties from being added to it, existing properties from being removed, prevents changing the enumerability, configurability, or writability of existing properties, and prevents the values of existing properties from being changed. In addition, freezing an object also prevents its prototype from being changed.

Implementations

impl IntegrityLevel

pub fn is_sealed(&self) -> bool

Returns true if the integrity level is sealed.

pub fn is_frozen(&self) -> bool

Returns true if the integrity level is frozen.

Trait Implementations

impl Clone for IntegrityLevel

fn clone(&self) -> IntegrityLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntegrityLevel

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

Formats the value using the given formatter.

impl PartialEq for IntegrityLevel

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

Tests for self and other values to be equal, and is used by ==.

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

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