Trait ExportKeyingMaterial 

pub trait ExportKeyingMaterial {
    // Required method
    fn export_keying_material<T: AsMut<[u8]>>(
        &self,
        output: T,
        label: &[u8],
        context: Option<&[u8]>,
    ) -> Option<T>;
}

Trait for extracting keying material from a TLS connection.

This allows anything that ends up potentially wrapping a TLS stream to use the underlying export_keying_material function. It is used during the relay handshake to establish a shared secret between the client and server for authentication purposes.

Required Methods

fn export_keying_material<T: AsMut<[u8]>>( &self, output: T, label: &[u8], context: Option<&[u8]>, ) -> Option<T>

If this type ends up wrapping a TLS stream, then this tries to export keying material by calling the underlying export_keying_material function.

However unlike that function, this returns Option, in case the underlying stream might not be wrapping TLS, e.g. as in the case of MaybeTlsStream.

For more information on what this function does, see the export_keying_material documentation.

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.
