Struct tss_esapi::structures::pcr_selection_list::PcrSelectionList

pub struct PcrSelectionList { /* fields omitted */ }

A struct representing a pcr selection list. This corresponds to the TSS TPML_PCR_SELECTION.

Implementations

impl PcrSelectionList

pub const MAX_SIZE: usize

pub fn len(&self) -> usize

Function for retrieiving the number of banks in the selection

pub fn is_empty(&self) -> bool

Returns true if the selection is empty.

pub fn list_from_option(pcr_list: Option<PcrSelectionList>) -> PcrSelectionList

Function for retrieving the PcrSelectionList from Option

This returns an empty list if None is passed

pub fn subtract(&mut self, other: &Self) -> Result<()>

Removes items in other from `self.

Arguments

• other - A PcrSelectionList containing items that will be removed from self.

Constraints

• Cannot be called with other that contains items that are not present in self.

• Cannot be called with other that contains pcr selection associated with a hashing algorithm that cannot be subtracted from the pcr selection associated with the same hashing algorithm in self.

Errors

• Calling the method with other that contains items not present in self will result in an InvalidParam error.

Examples

use tss_esapi::structures::{PcrSelectionListBuilder, PcrSlot};
use tss_esapi::interface_types::algorithm::HashingAlgorithm;
// pcr selections
let mut pcr_selection_list = PcrSelectionListBuilder::new()
    .with_size_of_select(Default::default())
    .with_selection(HashingAlgorithm::Sha256, &[PcrSlot::Slot0, PcrSlot::Slot8])
    .build();

// Another pcr selections
let other = PcrSelectionListBuilder::new()
    .with_size_of_select(Default::default())
    .with_selection(
        HashingAlgorithm::Sha256, &[PcrSlot::Slot0],
    )
    .build();
pcr_selection_list.subtract(&other).unwrap();
assert_eq!(pcr_selection_list.len(), 1);
