The subnet ID is the same as the root key, for local dfx. In Rust I wrote the conversion as:

/// Gets the subnet ID
#[context("Failed to determine subnet ID.")]
async fn get_subnet_id(agent: &Agent) -> anyhow::Result<Principal> {
    let root_key = agent
        .status()
        .await
        .with_context(|| "Could not get agent status")?
        .root_key
        .with_context(|| "Agent should have fetched the root key.")?;
    Ok(Principal::self_authenticating(root_key))
}
