Function i64x2_extract_lane

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

🔬This is a nightly-only experimental API. (simd_wasm64 #90599)

Available on target_family="wasm" and target feature simd128 and WebAssembly 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.
