Function pack_vector_lower 

pub fn pack_vector_lower(
    vector: Vector3D,
    non_finite: &str,
    out_of_range: &str,
) -> Result<[f32; 3], String>

Converts a vector to three f32 components, rounding every component toward negative infinity.

Arguments

• Vector3D - The vector to narrow.
• &str - The error message for a non-finite component.
• &str - The error message for an out-of-range component.

Returns

• Result<[f32; 3], String> - The narrowed components, or the first applicable error.
