Enum InitError 

pub enum InitError {
    BadMagic {
        actual: [u8; 3],
        expected: [u8; 3],
    },
    IncompatibleVersion(u8),
    InvalidLayout,
    OutOfMemory,
}

Error returned when RoaringBitmap::init rejects stable memory contents.

Variants

BadMagic

The first three bytes were not the expected RSB magic (see the crate::bitmap layout).

Fields

actual: [u8; 3]

expected: [u8; 3]

IncompatibleVersion(u8)

Header layout version is not supported by this build.

InvalidLayout

Catch-all for inconsistent header fields, snapshot length vs. memory size, corrupted snapshot bytes, or journal records that fail validation during replay.

This includes a journal slot count in the header (offset 12) that does not equal the build-time journal capacity—for example opening stable memory written by a build compiled with a different journal capacity.

OutOfMemory

RoaringBitmap::init on empty memory calls RoaringBitmap::new; bootstrap failures there (usually BitmapError::GrowFailed) are returned as this variant.

Trait Implementations

impl Debug for InitError

impl Eq for InitError

impl Error for InitError

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 InitError

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

Equality operator ==.

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