Struct Tpm2b 

pub struct Tpm2b<const CAPACITY: usize>(/* private fields */);

A zero-copy TPM2B wire view over caller-owned bytes.

Implementations

impl<const CAPACITY: usize> Tpm2b<CAPACITY>

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

Casts a byte slice into a TPM2B wire view.

Errors

Returns UnexpectedEnd when buf is shorter than the TPM2B header or declared payload size. Returns TrailingData when buf contains bytes after the declared payload. Returns TooManyBytes when the declared payload exceeds CAPACITY.

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

Casts the first TPM2B value in a byte slice into a wire view.

Errors

Returns Err(TpmError) when the first TPM2B value is malformed.

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

Casts a byte slice into a TPM2B wire view without validation.

Safety

The caller must ensure that buf contains exactly one complete TPM2B value and that its declared payload length does not exceed CAPACITY.

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

Casts a mutable byte slice into a mutable TPM2B wire view.

Errors

Returns UnexpectedEnd when buf is shorter than the TPM2B header or declared payload size. Returns TrailingData when buf contains bytes after the declared payload. Returns TooManyBytes when the declared payload exceeds CAPACITY.

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

Casts the first mutable TPM2B value in a byte slice into a wire view.

Errors

Returns Err(TpmError) when the first TPM2B value is malformed.

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

Casts a mutable byte slice into a mutable TPM2B wire view without validation.

Safety

The caller must ensure that buf contains exactly one complete TPM2B value and that its declared payload length does not exceed CAPACITY. The returned reference inherits the exclusive access represented by buf.

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

Returns the complete TPM2B byte representation.

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

Returns the complete mutable TPM2B byte representation.

pub fn size(&self) -> usize

Returns the declared payload size.

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

Returns the payload bytes.

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

Returns the payload bytes, as an alias for Self::data.

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

Returns the mutable payload bytes.

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

Returns the mutable payload bytes, as an alias for Self::data_mut.

pub const fn len(&self) -> usize

Returns the complete TPM2B wire length.

pub fn is_empty(&self) -> bool

Returns true when the TPM2B payload is empty.

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

Validates an exact TPM2B wire value.

Errors

Returns Err(TpmError) when the TPM2B value is malformed or has trailing data.

pub fn validate_prefix(buf: &[u8]) -> TpmResult<usize>

Validates the first TPM2B wire value and returns its wire length.

Errors

Returns Err(TpmError) when the first TPM2B value is malformed.
