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

Casts a byte slice into a fixed-size TPM wire view without validation.

Safety

The caller must ensure that buf.len() == N. Callers must also ensure any higher-level protocol invariants required by later typed accessors have been validated.

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

Casts a mutable byte slice into a fixed-size mutable TPM wire view without validation.

Safety

The caller must ensure that buf.len() == N. Callers must also ensure any higher-level protocol invariants required by later typed accessors have been validated. The returned reference inherits the exclusive access represented by buf.

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.

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.
