Trait ECPublicKeyBase 

pub trait ECPublicKeyBase: ECKey {
    // Required method
    fn uncompressed_public_key(&self) -> ECUncompressedPublicKey;
}

A trait for elliptic curve public keys that can provide their uncompressed form.

This trait extends ECKey to provide a method for obtaining the uncompressed representation of a public key. Elliptic curve public keys can be represented in both compressed (33 bytes) and uncompressed (65 bytes) formats:

• Compressed format: Uses a single byte prefix (0x02 or 0x03) followed by the x-coordinate (32 bytes), with the prefix indicating the parity of the y-coordinate.

• Uncompressed format: Uses a byte prefix (0x04) followed by both x and y coordinates (32 bytes each), for a total of 65 bytes.

The compressed format is more space-efficient and is recommended for most applications, but some legacy systems require the uncompressed format.

Required Methods

fn uncompressed_public_key(&self) -> ECUncompressedPublicKey

Returns the uncompressed public key representation.

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.
