Enum llvm_bitcursor::error::Error

#[non_exhaustive]
pub enum Error {
    Eof,
    InvalidLength,
    BadCast,
    InvalidReadSize,
    InvalidVbrWidth,
    Short,
}

All errors potentially produced by llvm-bitcursor APIs. Consumers should not attempt to match specific variants of this error type.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Eof

A read or other I/O operation encountered the end of the inner buffer.

InvalidLength

A user attempted to call BitCursor::new_with_len with an impossible length (larger that the supplied buffer).

BadCast

A generic API (e.g. BitCursor::read_as) was asked to read a value larger than the requested type could represent.

InvalidReadSize

A read API was called with an invalid bitsize (too small or large).

InvalidVbrWidth

A VBR read API was called with an invalid VBR width.

Short

An I/O operation completed partially, but the inner buffer ended before it full completion.

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
