Enum CTarget 

pub enum CTarget {
    HostC,
    RiscV,
    Tenstorrent,
    Cuda,
    Wasm,
}

A C-family lowering target, classified by whether it can express stackful coroutines. The concurrency knob is forced to ConcurrencyLowering::Stackless exactly when ucontext is absent.

Variants

HostC

The host C backend (gcc/clang) — full libc, ucontext available.

RiscV

The RISC-V AOT tier (runs under qemu with glibc) — ucontext available.

Tenstorrent

A Tenstorrent baby RISC-V core (glibc-backed C body) — ucontext available.

Cuda

A single CUDA <<<1,1>>> kernel — device code has NO ucontext/setjmp.

Wasm

The direct-WASM backend — no ucontext/setjmp in the sandbox.

Implementations

impl CTarget

pub fn has_ucontext(self) -> bool

Whether this target can express stackful coroutines (getcontext/makecontext/swapcontext). The single capability that forces the concurrency-lowering knob.

Trait Implementations

impl Clone for CTarget

fn clone(&self) -> CTarget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CTarget

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

Formats the value using the given formatter.

impl PartialEq for CTarget

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