Trait Implementations

impl Clone for Advice

fn clone(&self) -> Advice

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Advice

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Advice> for Advice

fn from(e: Advice) -> Advice

Converts to this type from the input type.

impl From<Advice> for u8

fn from(v: Advice) -> u8

Converts to this type from the input type.

impl<'a> GuestType<'a> for Advice

fn guest_size() -> u32

Returns the size, in bytes, of this type in the guest memory.

fn guest_align() -> usize

Returns the required alignment of this type, in bytes, for both guest and host memory.

fn read(location: &GuestPtr<'a, Self>) -> Result<Self, GuestError>

Reads this value from the provided ptr.

fn write(location: &GuestPtr<'_, Self>, val: Self) -> Result<(), GuestError>

Writes a value to ptr after verifying that ptr is indeed valid to store val.

impl PartialEq for Advice

fn eq(&self, other: &Advice) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<i32> for Advice

type Error = GuestError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Advice, GuestError>

Performs the conversion.

impl TryFrom<u8> for Advice

type Error = GuestError

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Advice, GuestError>

Performs the conversion.

impl Copy for Advice

impl StructuralPartialEq for Advice
