Enum PageTableMappingError 

pub enum PageTableMappingError {
    Unaligned,
    NotExist,
    Duplicated,
    InvalidPermission,
}

Page Table Mapping Error.

This enum represents errors that can occur when working with page table mappings in the virtual memory system. It is used to indicate specific issues that arise during memory address mapping operations, such as setting up or updating page tables.

Variants

Unaligned

Unaligned address.

This error is returned when an address provided for a page table entry is not properly aligned to the required page size. For example, the address might not be a multiple of 4KB (on x86_64 systems).

NotExist

Not exist.

This error is returned when a requested page table entry does not exist or is invalid. For instance, it could occur when trying to access an entry that is not present or has not been mapped yet.

Duplicated

Duplicated mapping.

This error is returned when an attempt is made to create a duplicate mapping for an address that already has an existing mapping.

InvalidPermission

Invalid permission.

This error is returned when an attempt is made to create a mapping with an invalid permission.

Trait Implementations

impl Debug for PageTableMappingError

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

Formats the value using the given formatter.

impl PartialEq for PageTableMappingError

fn eq(&self, other: &PageTableMappingError) -> 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.
