Description: Compile-time type information about arrays.

## Array

# Struct Array

Source

    #[non_exhaustive]pub struct Array {
        pub element_ty: TypeId,
        pub len: usize,
    }

Expand description

Compile-time type information about arrays.

## Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional `Struct { .. }` syntax; cannot be matched against without a wildcard `..`; and struct update syntax will not work.
§`element_ty: TypeId`
🔬This is a nightly-only experimental API. (`type_info` #146922)

The type of each element in the array.

§`len: usize`
🔬This is a nightly-only experimental API. (`type_info` #146922)

The length of the array.
