Enum MappingError 

pub enum MappingError {
    InvalidParam,
    AlreadyExists,
    BadState,
    NeedsRepair,
}

Error type for memory mapping operations.

Variants

InvalidParam

Invalid parameter (e.g., addr, size, flags, etc.)

AlreadyExists

The given range overlaps with an existing mapping.

BadState

The backend page table is in a bad state.

NeedsRepair

A fallible operation changed part of the materialized page table but could not prove that its inverse restored every preimage. Callers must quarantine the address-space range and repair it before reuse.

Trait Implementations

impl Debug for MappingError

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

impl Eq for MappingError

impl Error for MappingError

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 MappingError

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

Equality operator ==.

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

Inequality operator !=.
