Trait DecompactPoint 

pub trait DecompactPoint<C>: Sized
where
    C: Curve,
{
    // Required method
    fn decompact(
        x: &GenericArray<u8, <C as Curve>::FieldBytesSize>,
    ) -> CtOption<Self>;
}

Decompact an elliptic curve point from an x-coordinate.

Decompaction relies on properties of specially-generated keys but provides a more compact representation than standard point compression.

Required Methods

fn decompact( x: &GenericArray<u8, <C as Curve>::FieldBytesSize>, ) -> CtOption<Self>

Attempt to decompact an elliptic curve point

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.

Implementations on Foreign Types
