Struct ShapeMismatchContext 

pub struct ShapeMismatchContext { /* private fields */ }

Diagnostic context attached to shape-mismatch errors.

This struct provides a builder-style API for constructing descriptive FerroError::ShapeMismatch errors.

Examples

use ferrolearn_core::error::ShapeMismatchContext;

let ctx = ShapeMismatchContext::new("predict input")
    .expected(&[100, 10])
    .actual(&[100, 5]);
let err = ctx.build();
assert!(err.to_string().contains("predict input"));

Implementations

impl ShapeMismatchContext

pub fn new(context: impl Into<String>) -> Self

pub fn expected(self, shape: &[usize]) -> Self

Set the expected shape.

pub fn actual(self, shape: &[usize]) -> Self

Set the actual shape.

pub fn build(self) -> FerroError

Build the FerroError::ShapeMismatch error.
