Enum llvm_bitstream::error::Error

}

All possible errors that can occur while parsing a bitstream.

Variants

Exhausted

The underlying bitstream has no more data to parse.

Cursor

The underlying BitCursor returned an error that we couldn’t specialize.

Tuple Fields of Cursor

0: CursorError

BadContainer

We couldn’t parse the wrapper structure or other data that precedes the actual bitstream.

Tuple Fields of BadContainer

0: String

BadBlockInfoCode

A record in the BLOCKINFO block has a code that we don’t know. BLOCKINFO must be fully interpreted in order to correctly parse the remainder of the bitstream, so this is a hard error.

Tuple Fields of BadBlockInfoCode

0: TryFromPrimitiveError<BlockInfoCode>

BadAbbrevOpEnc

An operand in a DEFINE_ABBREV definition has a code that we don’t know. This indicates either a malformed bitstream or a new operand format that we don’t yet support, so it’s a hard error.

Tuple Fields of BadAbbrevOpEnc

0: TryFromPrimitiveError<AbbrevOpEnc>

BadValue

A field value is either invalid or the incorrect type for a particular context.

Tuple Fields of BadValue

0: String

StreamParse

A generic error occurred while parsing the bitstream.

Tuple Fields of StreamParse

0: String

AbbrevParse

An error occurred while interpreting a DEFINE_ABBREV record.

Tuple Fields of AbbrevParse

0: String

BadAbbrev

An error occurred while mapping an abbreviated record back to its abbreviation definition.

Tuple Fields of BadAbbrev

0: u64

Scope

An error occurred during block scope entrance or exit.

Tuple Fields of Scope

0: String

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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 description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
