# Function v128_load64_lane

Source

    pub unsafe fn v128_load64_lane<const L: usize>(v: v128, m: *const u64) -> v128

🔬This is a nightly-only experimental API. (`simd_wasm64` #90599)
Available on `target_family=wasm` and target feature `simd128` only.
Expand description

Loads a 64-bit value from `m` and sets lane `L` of `v` to that value.

This intrinsic is provided for completeness and is equivalent to `u64x2_replace_lane::<L>(v, *m)` (which doesn’t require `unsafe`).

## §Unsafety

This intrinsic is unsafe because it takes a raw pointer as an argument, and the pointer must be valid to load 8 bytes from. Note that there is no alignment requirement on this pointer since this intrinsic performs a 1-aligned load.
