Trait ArrayRef

pub trait ArrayRef<'a>: Copy {
    type JsonRef: JsonRef<'a>;

    // Required methods
    fn len(self) -> usize;
    fn get(self, index: usize) -> Option<Self::JsonRef>;
    fn list(self) -> Vec<Self::JsonRef>;

    // Provided method
    fn is_empty(self) -> bool { ... }
}

A trait for borrowed JSON arrays.

Required Associated Types

type JsonRef: JsonRef<'a>

The type of borrowed JSON values.

Required Methods

fn len(self) -> usize

Returns the length of the array.

fn get(self, index: usize) -> Option<Self::JsonRef>

Returns the value at the given index.

fn list(self) -> Vec<Self::JsonRef>

Returns all values in the array.

Provided Methods

fn is_empty(self) -> bool

Returns true if the array is empty.

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.
