Struct TpmResponse 

pub struct TpmResponse(/* private fields */);

A zero-copy TPM response wire view over caller-owned bytes.

Implementations

impl TpmResponse

pub fn cast(buf: &[u8]) -> TpmResult<&Self>

Casts a byte slice into a TPM response wire view.

Errors

Returns Err(TpmProtocolError) when the response envelope is malformed.

pub unsafe fn cast_unchecked(buf: &[u8]) -> &Self

Casts a byte slice into a TPM response wire view without validation.

Safety

The caller must ensure that buf contains exactly one complete TPM response frame.

pub fn cast_mut(buf: &mut [u8]) -> TpmResult<&mut Self>

Casts a mutable byte slice into a mutable TPM response wire view.

Errors

Returns Err(TpmProtocolError) when the response envelope is malformed.

pub unsafe fn cast_mut_unchecked(buf: &mut [u8]) -> &mut Self

Casts a mutable byte slice into a mutable TPM response wire view without validation.

Safety

The caller must ensure that buf contains exactly one complete TPM response frame. The returned reference inherits the exclusive access represented by buf.

pub const fn as_bytes(&self) -> &[u8]

Returns the complete response frame bytes.

pub fn as_bytes_mut(&mut self) -> &mut [u8]

Returns the mutable response frame bytes.

pub fn tag(&self) -> TpmResult<TpmSt>

Returns the response tag.

Errors

Returns VariantNotAvailable when the tag value is not defined.

pub fn size(&self) -> u32

Returns the response frame size field.

pub fn rc(&self) -> TpmResult<TpmRc>

Returns the response code.

Errors

Returns Err(TpmProtocolError) when the response code is malformed.

pub fn set_tag(&mut self, tag: TpmSt)

Sets the response tag without changing the frame shape.

pub fn set_rc(&mut self, rc: TpmRc)

Sets the response code without changing the frame shape.

pub fn body(&self) -> &[u8]

Returns the response body bytes after the TPM header.

pub fn body_mut(&mut self) -> &mut [u8]

Returns the mutable response body bytes after the TPM header.

pub fn validate(&self, cc: TpmCc) -> TpmResult<()>

Validates response frame structure without constructing an owned response body.

Errors

Returns Err(TpmProtocolError) when the response frame is malformed or cc has no dispatch entry.

pub const fn is_empty(&self) -> bool

Returns true when the response frame contains no bytes.

pub const fn len(&self) -> usize

Returns the response frame length.

Trait Implementations

impl AsMut<[u8]> for TpmResponse

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[u8]> for TpmResponse

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl TpmCast for TpmResponse

fn cast(buf: &[u8]) -> TpmResult<&Self>

Casts buf into Self after validating the wire-view invariants.

unsafe fn cast_unchecked(buf: &[u8]) -> &Self

Casts buf into Self without validating the wire-view invariants.

impl TpmCastMut for TpmResponse

fn cast_mut(buf: &mut [u8]) -> TpmResult<&mut Self>

Casts buf into mutable Self after validating the wire-view invariants.

unsafe fn cast_mut_unchecked(buf: &mut [u8]) -> &mut Self

Casts buf into mutable Self without validating the wire-view invariants.
