Struct EncodeHints 

pub struct EncodeHints {
    pub wide: Option<bool>,
    pub bpf_call_local: Option<bool>,
}

Per-call encoding hints that arches interpret in their own convention. Today the only hint is wide (x86’s short-vs-rel32 toggle); fixed-width arches (BPF, AArch64) ignore it.

Kept as a plain struct rather than per-method args so the trait can grow new hints without breaking every impl.

Fields

wide: Option<bool>

Force a wide-form encoding. On x86 this means “use rel32 even when rel8 would fit”; on BPF this is ignored (slot offsets are always one slot wide). None = arch picks.

bpf_call_local: Option<bool>

BPF call-convention hint for encode_call: Some(true) requests call_local (opcode 0x8d, Linux eBPF style), Some(false) requests call_internal (opcode 0x85 src=1, Solana sBPF style), None defers to the codec’s default. Lifters that have the original opcode (e.g. the byte-drop pass with pinned bytes) set this so the regen matches the original encoding exactly. Ignored by non-BPF arches.

Implementations

impl EncodeHints

pub const fn wide(wide: bool) -> Self

Convenience: hints with wide set.

pub fn wide_or(self, default: bool) -> bool

Resolve wide with a default for arches that need a bool. Most callers don’t care about the default; BPF ignores wide entirely, x86 falls back to “pick shortest.”
