Crate tpm2_protocol 

TPM 2.0 Protocol

A library for marshaling and unmarshaling TCG TPM 2.0 protocol messages.

Constraints

• alloc is disallowed.
• Dependencies are disallowed.
• Developer dependencies are disallowed.
• Panics are disallowed.

Design Goals

• The crate must compile with GNU make and rustc without any external dependencies.

Zero-Copy Contract

Read-side protocol APIs operate on caller-owned byte slices and return borrowed wire views into those slices. Implementations must not copy payload bytes to inspect frames or nested TPM values. Scalar fields may be read by value from their big-endian wire representation.

Validation must prove all exposed borrowed views are bounded by the original input slice. Any malformed length, tag, selector, or trailing byte condition must be reported as TpmError instead of panicking.

The crate does not use the external zerocopy crate.

Additional structured data for a TPM protocol error.

TpmWire

A byte-backed TPM wire view.

TpmWireBytes

Traits

TpmCast

Casts caller-owned bytes into a TPM wire view.

TpmCastMut

Casts caller-owned mutable bytes into a mutable TPM wire view.

TpmField

Reads one field from a TPM wire structure.

TpmMarshal

TpmSized

Provides two ways to determine the size of an oBject: a compile-time maximum and a runtime exact size.

TpmTaggedField

Reads a union field selected by a previously-read tag.
