Trait OutputSizeMethods 

trait OutputSizeMethods {
    // Required method
    fn from_contraction_and_shapes(
        contraction: &Contraction,
        operand_shapes: &[Vec<usize>],
    ) -> Result<HashMap<char, usize>, &'static str>;
}

Enables OutputSize::from_contraction_and_shapes()

Required Methods

fn from_contraction_and_shapes( contraction: &Contraction, operand_shapes: &[Vec<usize>], ) -> Result<HashMap<char, usize>, &'static str>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl OutputSizeMethods for HashMap<char, usize>

fn from_contraction_and_shapes( contraction: &Contraction, operand_shapes: &[Vec<usize>], ) -> Result<Self, &'static str>
