Enum BitmapError 

#[non_exhaustive]
pub enum BitmapError {
    TooSmall,
    InvalidHeader,
    MissingFullDag,
    FileChecksumMismatch,
    PackChecksumMismatch,
    Corrupt,
    InvalidEwah,
    Io(String),
}

Failure mode when a .bitmap sidecar cannot be used.

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.

TooSmall

The file is empty or shorter than a bitmap header.

InvalidHeader

The BITM signature or version is wrong.

MissingFullDag

Required BITMAP_OPT_FULL_DAG is missing.

FileChecksumMismatch

On-disk trailer hash does not match file contents.

PackChecksumMismatch

Header pack/MIDX checksum does not match the object database.

Corrupt

An extension or entry could not be parsed safely.

InvalidEwah

Embedded EWAH payload is invalid.

Io(String)

I/O while mapping or reading the bitmap file.

Trait Implementations

impl Clone for BitmapError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BitmapError

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

Formats the value using the given formatter.

impl Display for BitmapError

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

Formats the value using the given formatter.

impl Eq for BitmapError

impl Error for BitmapError

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 From<BitmapError> for BitmapWalkError

fn from(source: BitmapError) -> Self

Converts to this type from the input type.

impl PartialEq for BitmapError

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

Equality operator ==.

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

Inequality operator !=.
