Enum LoweredArgSnapshot 

pub enum LoweredArgSnapshot {
    I32(i32),
    I64(i64),
    F32(f32),
    F64(f64),
    U32(u32),
    U64(u64),
    Ptr {

        guest_offset: u32,
    },
}

Pointer-free, freely-Send/Sync snapshot of a LoweredArg.

LoweredArgSnapshot is the shape the public observability surface (crate::host::WasiCudaContext::last_lowered_args) hands out. It mirrors every variant of LoweredArg except that the Ptr variant drops the raw host_ptr field — only the guest_offset and len the guest declared survive.

The redaction is deliberate, not cosmetic. The host-side raw pointer inside a LoweredArg::Ptr is only valid while the guest’s linear memory has not been reallocated; a memory.grow between launch and readback would dangle it. Stripping the field at the public boundary makes that use-after-grow unrepresentable for embedders, and also removes the only reason LoweredArg itself cannot implement Sync.

Variants

I32(i32)

32-bit signed scalar.

I64(i64)

64-bit signed scalar.

F32(f32)

32-bit float scalar.

F64(f64)

64-bit float scalar.

U32(u32)

32-bit unsigned scalar.

U64(u64)

64-bit unsigned scalar.

Ptr

Pointer argument with the host pointer redacted; only the guest-declared (guest_offset, len) pair survives.

Fields

len: u32

Byte length the kernel will access.

guest_offset: u32

Original guest-memory offset (for logging / tests).

Trait Implementations

impl Clone for LoweredArgSnapshot

fn clone(&self) -> LoweredArgSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LoweredArgSnapshot

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

Formats the value using the given formatter.

impl From<&LoweredArg> for LoweredArgSnapshot

fn from(arg: &LoweredArg) -> Self

Converts to this type from the input type.

impl PartialEq for LoweredArgSnapshot

fn eq(&self, other: &LoweredArgSnapshot) -> 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.
