Trait Implementations

impl Clone for Whence

fn clone(&self) -> Whence

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Whence

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

Formats the value using the given formatter.

impl From<Whence> for Whence

fn from(e: Whence) -> Whence

Converts to this type from the input type.

impl From<Whence> for u8

fn from(v: Whence) -> u8

Converts to this type from the input type.

impl GuestType for Whence

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( mem: &GuestMemory<'_>, location: GuestPtr<Self>, ) -> Result<Self, GuestError>

Reads this value from the provided ptr.

fn write( mem: &mut GuestMemory<'_>, 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 Whence

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<i32> for Whence

type Error = GuestError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl TryFrom<u8> for Whence

type Error = GuestError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl Copy for Whence

impl StructuralPartialEq for Whence
