Struct sallyport::guest::alloc::Input

pub struct Input<'a, T: ?Sized, U> { /* private fields */ }

Allocated input.

Implementations

impl<'a, T: ?Sized, U> Input<'a, T, U>

pub unsafe fn new_unchecked(data_ref: InRef<'a, T>, val: U) -> Self

Contructs a new Input.

Safety

Callers must ensure that the passed reference and value have the same size.

impl<T: ?Sized, U> Input<'_, T, U>

pub fn offset(&self) -> usize

Returns the byte offset within block.

impl<T, U> Input<'_, [T], U>

pub fn len(&self) -> usize

Returns the number of allocated elements of type T.

impl<'a, T, U: Borrow<T>> Input<'a, T, U>

pub fn stage(alloc: &mut impl Allocator, val: U) -> Result<Self>

Attempts to allocate input segment to fit val in the block and returns the resulting Input on success.

impl<'a, T, U: AsRef<[T]>> Input<'a, [T], U>

pub fn stage_slice(alloc: &mut impl Allocator, val: U) -> Result<Self>

Attempts to allocate input segment to fit val.len() elements of val in the block and returns the resulting Input on success.

impl<'a, T> Input<'a, [T], &'a [T]>

pub fn stage_slice_max(
    alloc: &mut impl Allocator,
    val: &'a [T]
) -> Result<(Self, &'a [T])>

Attempts to allocate input segment to fit as many elements of val in the block as capacity allows and returns the resulting Input on success.
