Struct GotExpected 

pub struct GotExpected<T> {
    pub got: T,
    pub expected: T,
}

A mismatch between an expected value and the actual value found.

Inspired by reth’s GotExpected<T> pattern — useful for version conflicts, quantity mismatches, and other “expected X but got Y” scenarios.

Example

use stateset_core::errors::GotExpected;

let mismatch = GotExpected { got: 3, expected: 5 };
assert_eq!(mismatch.to_string(), "expected 5, got 3");

Fields

got: T

The value that was actually found.

expected: T

The value that was expected.
