Function check_tree_head 

pub async fn check_tree_head(
    client: &Client,
    base_url: &Url,
    pub_key: &PKey<Public>,
) -> Result<SignedTreeHead, Error>

Check, verify and return the latest tree head from the CT log at base_url.

This function is only useful to those who want to do some custom CT API calling. CTClient will automatically update its cache of tree root. If you use CTClient, call CTClient::get_checked_tree_head instead.

Params

• client: A reqwest::Client instance. See CTClient::get_reqwest_client
