# [−][src]Function core::arch::wasm32::i64x2_extract_lane

    pub unsafe fn i64x2_extract_lane<const N: usize>(a: v128) -> i64

🔬 This is a nightly-only experimental API. (`wasm_simd` #74372)
This is supported on WebAssembly and target feature `simd128` only.

Extracts a lane from a 128-bit vector interpreted as 2 packed i64 numbers.

Extracts the scalar value of lane specified in the immediate mode operand `N` from `a`. If `N` is out of bounds then it is a compile time error.
