    pub unsafe fn f32x4_extract_lane(a: v128, imm: usize) -> f32

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on WebAssembly only.

Extracts a lane from a 128-bit vector interpreted as 4 packed f32 numbers.

Extracts the scalar value of lane specified in the immediate mode operand `imm` from `a`.
