Expand description
Errors while parsing the PE binary.
Variants
Null
Null address.
Bounds
Out of bounds.
Catch-all for bounds check errors.
ZeroFill
Data is not available.
Can happen when referencing data in PeFile
instances.
Sections can be shorter than stored on disk, the remaining bytes will default to zeroes when loaded by the system. Since these zeroes would just be a waste of space, they are not present in the binaries on disk. This error happens when attempting to get a reference to such zero filled data.
Unmapped
Data is not available.
Can happen when referencing data in PeView
instances.
Sections can have excess in their raw data which won’t be mapped when loaded by the system. This error happens when attempting to get a reference to such unmapped raw data. Sometimes this kind of excess is called an overlay.
Misaligned
Address is misaligned.
BadMagic
Expected magic number does not match.
PeMagic
Trying to load a PE32 file with a PE32+ parser or vice versa.
Insanity
Sanity check failed.
Some value was so far outside its typical range, while not technically incorrect, probably indicating something went wrong. If this error is encountered legitimately, create an issue or file a PR to relax the artificial restrictions.
Invalid
Invalid data.
Structured data was found which simply isn’t valid. Catch-all for errors which don’t fall under other errors.
Overflow
Overflow error.
Catch-all for overflow and underflow errors.
Encoding
Encoding error.
Catch-all for string related errors such as lacking a nul terminator.
Aliasing
Aliasing error.
Request cannot be fulfilled because it would alias with an existing borrow.
Implementations
sourceimpl Error
impl Error
sourcepub fn is_null(self) -> bool
pub fn is_null(self) -> bool
Returns if the error variant is Null.
Useful in match guards where Null
should be handled as a non-error case.
fn with_default(result: pelite::Result<i32>) -> pelite::Result<i32> {
let i = match result {
Ok(i) => i,
// Avoids a more verbose comparison with pelite::Error::Null
Err(err) if err.is_null() => 0,
Err(err) => return Err(err),
};
Ok(i)
}
assert_eq!(with_default(Err(pelite::Error::Null)), Ok(0));
