Type Alias s2n_tls_sys::s2n_psk_selection_callback

pub type s2n_psk_selection_callback = Option<unsafe extern "C" fn(conn: *mut s2n_connection, context: *mut c_void, psk_list: *mut s2n_offered_psk_list) -> c_int>;

Callback function to select a PSK from a list of offered PSKs. Use this callback to implement custom PSK selection logic. The s2n-tls default PSK selection logic chooses the first matching PSK from the list of offered PSKs sent by the client.

Safety

context is a void pointer and the caller is responsible for ensuring it is cast to the correct type. After the completion of this callback, the pointer to psk_list is invalid.

@param conn A pointer to the s2n_connection object. @param context A pointer to a context for the caller to pass state to the callback, if needed. @param psk_list A pointer to the offered PSK list being read.
