Trait KeyingMaterialExporter 

pub trait KeyingMaterialExporter {
    // Required method
    fn export_keying_material(
        &self,
        label: &str,
        context: &[u8],
        length: usize,
    ) -> Result<Vec<u8>>;
}

KeyingMaterialExporter to extract keying material.

This trait sits here to avoid getting a direct dependency between the dtls and srtp crates.

Required Methods

fn export_keying_material( &self, label: &str, context: &[u8], length: usize, ) -> Result<Vec<u8>>

Derives keying material from the established session, per RFC 5705.

label and context bind the derived key to a purpose — DTLS-SRTP uses the EXTRACTOR-dtls_srtp label to obtain SRTP master keys and salts from a completed DTLS handshake.

Errors

Fails if the session has not completed its handshake, so no secret is available yet.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
