Type Alias DataRefType

pub type DataRefType<'a, const N: usize> = Option<&'a [u8; N]>;

DataRefType is a type alias for an optional reference to a fixed-size array of u8 bytes.

This type is similar to DataType, but instead of owning the key, it holds a reference to a fixed-size array of u8 bytes, which is useful when the key data is borrowed rather than owned. It is also parameterized by a constant generic N, allowing different sizes of keys to be used with a single type.

DataRefType is typically used when the key is stored elsewhere in memory, and you want to reference it without copying or taking ownership of the data. This is useful for scenarios where the key data already exists and you need to work with it without transferring ownership.

Example:

let key_ref: DataRefType<4> = Some(&[1, 2, 3, 4]);

Fields:

• Some(&[u8; N]): A reference to a fixed-size array of u8 bytes representing the key.
• None: Indicates that the key is not present.

Type Parameters:

• N: The fixed length of the key array (i.e., the number of u8 bytes in the key).

Traits Implemented:

• Implements Option, meaning it can be Some containing a reference to a key or None for a missing key

Aliased Type
