Enum MapError 

pub enum MapError {
    AddressRange(VirtualAddress),
    InvalidVirtualAddress(VirtualAddress),
    RegionBackwards(MemoryRegion),
    PteUpdateFault(usize),
    InvalidFlags(Attributes),
    BreakBeforeMakeViolation(MemoryRegion),
}

An error attempting to map some range in the page table.

Variants

AddressRange(VirtualAddress)

The address requested to be mapped was out of the range supported by the page table configuration.

InvalidVirtualAddress(VirtualAddress)

The address requested to be mapped was not valid for the mapping in use.

RegionBackwards(MemoryRegion)

The end of the memory region is before the start.

PteUpdateFault(usize)

There was an error while updating a page table entry.

InvalidFlags(Attributes)

The requested flags are not supported for this mapping

BreakBeforeMakeViolation(MemoryRegion)

Updating the range violates break-before-make rules and the mapping is live

Trait Implementations

impl Clone for MapError

fn clone(&self) -> MapError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MapError

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

Formats the value using the given formatter.

impl Display for MapError

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

Formats the value using the given formatter.

impl Error for MapError

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 MapError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
