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".

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>
