}

Errors that can occur while demangling a symbol.

Variants

UnexpectedEnd

The mangled symbol ends abruptly.

UnexpectedText

The mangled symbol is not well-formed.

BadBackReference

Found a back reference that is out-of-bounds of the substitution table.

BadTemplateArgReference

Found a reference to a template arg that is either out-of-bounds, or in a context without template args.

ForwardTemplateArgReference

Found a reference to a template arg from within the arg itself (or from within an earlier arg).

BadFunctionArgReference

Found a reference to a function arg that is either out-of-bounds, or in a context without function args.

BadLeafNameReference

Found a reference to a leaf name in a context where there is no current leaf name.

Overflow

An overflow or underflow would occur when parsing an integer in a mangled symbol.

TooMuchRecursion

Encountered too much recursion when demangling symbol.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
