Enum UnifError 

#[non_exhaustive]
pub enum UnifError {
    HeaderTruncated(usize),
    BadMagic([u8; 4]),
    ChunkOverrun {
        id: String,
        offset: usize,
        len: usize,
    },
    NoMapr,
    UnknownBoard(String),
}

Errors from parsing a UNIF container.

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.

HeaderTruncated(usize)

Shorter than the 32-byte fixed header.

BadMagic([u8; 4])

The magic prefix is not "UNIF".

ChunkOverrun

A chunk’s declared length runs past the end of the file.

Fields

id: String

4-char chunk id.

offset: usize

Byte offset of the chunk header.

len: usize

Declared payload length.

NoMapr

No MAPR board-name chunk was present.

UnknownBoard(String)

The MAPR board name does not resolve to a known iNES mapper.

Trait Implementations

impl Debug for UnifError

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

Formats the value using the given formatter.

impl Display for UnifError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for UnifError

impl Error for UnifError

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

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for UnifError

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
