Struct Mismatch 

#[non_exhaustive]
pub struct Mismatch {
    pub module: &'static str,
    pub rva: u32,
    pub expected: &'static [u8],
    pub found: Vec<u8>,
    pub scan: Option<Error>,
    pub vtable: Option<VtableMiss>,
}

Why a function wasn’t where the bindings expect, and why nothing else found it: the details of Error::VerificationFailed.

Boxed, so the error stays small as ways to find a function are added.

Examples

use imping_runtime::{Error, VtableMiss};

if let Error::VerificationFailed(mismatch) = &error {
    if let Some(VtableMiss::ClassNotFound { type_name }) = &mismatch.vtable {
        eprintln!("{type_name} is gone from this build");
    }
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

module: &'static str

The module’s file name.

rva: u32

The function’s address relative to the module’s base.

expected: &'static [u8]

The bytes the bindings expect.

found: Vec<u8>

The bytes found, empty if they’d be past the end of the module.

scan: Option<Error>

Why the function’s byte pattern didn’t find it, if it has one and that’s why.

vtable: Option<VtableMiss>

Why its class’s vtable didn’t lead to it, if it’s in one.
