Struct r2d2_cryptoki::SessionManager

pub struct SessionManager { /* private fields */ }

Manager holding all information necessary for opening new connections

Implementations

impl SessionManager

pub fn new(pkcs11: Pkcs11, slot: Slot, session_type: SessionType) -> Self

Example

 let mut pkcs11 = Pkcs11::new("libsofthsm2.so").unwrap();
 pkcs11 .initialize(CInitializeArgs::OsThreads).unwrap();
 let slots = pkcs11.get_slots_with_token().unwrap();
 let slot = slots.first().unwrap();
 let manager = SessionManager::new(pkcs11, *slot, SessionType::RwUser(Pin::new("abcd".to_string())));

pub fn max_size(&self, maximum: u32) -> Result<Option<u32>, Error>

Returns the maximum number of sessions supported by the HSM.

Arguments:

• maximum: A maximum number of sessions as max_size can return u32::max_value() which is probably more than what your application should use.

Example

 let pool_builder = r2d2::Pool::builder();
 let pool_builder = if let Some(max_size) = manager.max_size(100).unwrap() {
    pool_builder.max_size(max_size)
 } else {
    pool_builder
 };
 let pool = pool_builder.build(manager).unwrap();
