Struct TpmConfig 

pub struct TpmConfig {
    pub device: Option<PathBuf>,
    pub hierarchy: Hierarchy,
    pub parent_handle: Option<ParentHandle>,
    pub parent_password: Vec<u8>,
}

Resolved configuration for the TPM backend.

Produced by TpmConfig::from_options; consumed by [crate::backend::TpmBackend::open]. Holds the post-parse, typed form of every option the backend reads, so the open path does not re-do string parsing on every call.

Fields

device: Option<PathBuf>

Path to the TPM device. None means “let tss-esapi auto-detect” (the common case on Linux where tcti=tabrmd finds the system TPM ResourceManager).

hierarchy: Hierarchy

Hierarchy the parent key lives under.

parent_handle: Option<ParentHandle>

Persistent handle of the parent (wrapping) key. May be None at config time — the backend will then create a transient parent on the fly and evict it on close. Persistent handles survive reboot and are the production setting.

parent_password: Vec<u8>

Authorisation value for the parent key. Empty by default (matches the typical owner-hierarchy deployment).

Implementations

impl TpmConfig

pub fn from_options(opts: &Options) -> Result<Self>

Parse the backend config out of the Options string map. Unknown keys are ignored; malformed values surface as [Error::Wrapped].

Trait Implementations

impl Clone for TpmConfig

fn clone(&self) -> TpmConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TpmConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TpmConfig

fn default() -> Self

Returns the “default value” for a type.

impl Eq for TpmConfig

impl PartialEq for TpmConfig

fn eq(&self, other: &TpmConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
