A trait for types that can be used as array elements

Required Associated Constants

const NAME: &'static str

The type name

const SYMBOL: char

A glyph indicating the type

const TYPE_ID: u8

An ID for the type

Required Methods

fn get_scalar_fill(fill: &Fill<'_>) -> Result<FillValue<Self>, &'static str>

Get the scalar fill value from the environment

fn get_array_fill( fill: &Fill<'_>, ) -> Result<FillValue<Array<Self>>, &'static str>

Get the array fill value from the environment

fn array_hash<H: Hasher>(&self, hasher: &mut H)

Hash the value

fn proxy() -> Self

Get the proxy value

Provided Methods

fn nested_value(&self) -> Option<&Value>

Get a nested value

fn has_wildcard(&self) -> bool

Check if this element has the wildcard value

fn sort_list(list: &mut [Self], up: bool)

Sort a list of this type

fn is_sortable(&self) -> bool

Whether this value can be sorted

fn dbg_validate(arr: &Array<Self>)

Validate array correctness in debug mode

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.
