Enum VectorOperand 

#[non_exhaustive]
pub enum VectorOperand {
    Left,
    Right,
}

Operand of a binary vector operation.

Identifies which input needs correction when LaError::ZeroVector or NonFiniteLocation::VectorOperandEntry reports an invalid direction or coordinate, including errors from crate::VectorAngle::angle.

Examples

use la_stack::prelude::*;

match [1.0, 0.0].as_slice().angle(&[0.0, -0.0]) {
    Err(LaError::ZeroVector { operand, .. }) => {
        assert_eq!(operand, VectorOperand::Right);
    }
    _ => unreachable!("the right input is an all-zero vector"),
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Left

Left operand (self for a method).

Right

Right operand (the method argument).
