Struct tpm2::Simulator

pub struct Simulator {
    pub(crate) _priv: (),
}

A libtpm2-based TPM simulator.

At most one simulator may exist per process because libtpm2 uses a static global response buffer.

Examples

let mut simulator = tpm2::Simulator::singleton_in_current_directory();

let command = &[ /* ... */ ];
let response = simulator.execute_command(command);
println!("{:?}", response);

Fields

_priv: ()

Implementations

impl Simulator

pub fn singleton_in_current_directory() -> Self

Initializes a TPM simulator in the current working directory.

Panics

Panics if a TPM simulator has already been initialized by this process.

pub fn execute_command<'a>(&'a mut self, command: &[u8]) -> &'a [u8]

Sends a TPM command to the TPM simulator, waits for the work to be performed, and receives back the TPM response.

Executing a command requires exclusive access to the TPM simulator because it mutates libtpm2 static state.

The returned response buffer remains valid until the next TPM command is executed.
