Struct TpmWireBytes 

pub struct TpmWireBytes<const N: usize>(/* private fields */);

A byte-backed TPM wire view with a fixed byte length.

Implementations

impl<const N: usize> TpmWireBytes<N>

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

Casts a byte slice into a fixed-size TPM wire view.

Errors

Returns UnexpectedEnd when buf is smaller than N bytes. Returns TrailingData when buf is larger than N bytes.

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

Validates an exact fixed-size TPM wire view.

Errors

Returns UnexpectedEnd when buf is smaller than N bytes. Returns TrailingData when buf is larger than N bytes.

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

Validates that buf starts with a fixed-size TPM wire view.

Errors

Returns UnexpectedEnd when buf is smaller than N bytes.

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

Casts the first N bytes into a fixed-size TPM wire view.

Errors

Returns UnexpectedEnd when buf is smaller than N bytes.

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

Casts a mutable byte slice into a fixed-size mutable TPM wire view.

Errors

Returns UnexpectedEnd when buf is smaller than N bytes. Returns TrailingData when buf is larger than N bytes.

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

Casts the first N mutable bytes into a fixed-size TPM wire view.

Errors

Returns UnexpectedEnd when buf is smaller than N bytes.

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

Returns the backing bytes.

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

Returns the mutable backing bytes.

pub const fn len(&self) -> usize

Returns the number of backing bytes.

pub const fn is_empty(&self) -> bool

Returns true when the backing byte array is empty.

impl<const N: usize> TpmWireBytes<N>

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

Casts a byte slice into this wire view without validation.

Safety

The caller must ensure buf satisfies every invariant required by the checked constructors for this view.

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

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

Safety

The caller must ensure buf satisfies every invariant required by the checked constructors for this view. The returned reference inherits the exclusive access represented by buf.

Trait Implementations

impl<const N: usize> AsMut<[u8]> for TpmWireBytes<N>

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

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

impl<const N: usize> AsRef<[u8]> for TpmWireBytes<N>

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

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

impl<const N: usize> TpmCast for TpmWireBytes<N>

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

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

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

Casts the first wire value in buf into Self and returns the remainder.

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

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

impl<const N: usize> TpmCastMut for TpmWireBytes<N>

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

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

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

Casts the first mutable wire value in buf into Self and returns the remainder.

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

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