Error type for memf-core operations.

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.

Physical(Error)

Physical memory read error.

Symbol(Error)

Symbol resolution error.

PageNotPresent(u64)

Page table entry not present (page fault).

PartialRead

Read crossed a page boundary and the next page is not mapped.

Fields

addr: u64

Virtual address of the read.

requested: usize

Bytes requested.

got: usize

Bytes actually read.

MissingSymbol(String)

A required symbol or field was not found.

SizeMismatch

Type size mismatch during Pod cast.

Fields

expected: usize

Expected size in bytes.

got: usize

Actual size available.

ListCycle(usize)

The list walk exceeded the maximum iteration count (cycle protection).

PagedOut

Page is in a pagefile that was not provided.

Fields

vaddr: u64

Virtual address of the faulting page.

pagefile_num: u8

Pagefile number (0 = pagefile.sys, 1-15 = secondary).

page_offset: u64

Page offset within the pagefile.

PrototypePte(u64)

Page uses a prototype PTE (shared section, not yet supported).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
