Required Methods

fn get_type(&self) -> ObjectType

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

fn has_index(&self, idx: usize) -> bool

fn at_index<'a>(&'a self, idx: usize) -> Result<Option<&'a Self>>

fn at_index_mut<'a>(&'a mut self, idx: usize) -> Result<Option<&'a mut Self>>

fn at_key<'a>(&'a self, key: &str) -> Result<Option<&'a Self>>

fn at_key_mut<'a>(&'a mut self, key: &str) -> Result<Option<&'a mut Self>>

fn array_len(&self) -> Option<usize>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
