Enum MappingSource 

pub enum MappingSource {
    Anonymous(AnonymousSource),
    File(FileSource),
    External(ExternalSource),
    Linear(LinearSource),
}

Origin of a mapping. The payload types keep source-specific metadata out of the VMA interval tree while still making a source transition explicit.

Variants

Anonymous(AnonymousSource)

File(FileSource)

External(ExternalSource)

Linear(LinearSource)

Implementations

impl MappingSource

pub const fn key(self) -> u64

Stable source key used to preserve a mapping group across VMA splits. The key is metadata-only; it never encodes a pointer or an allocator address, so it remains valid when a page-cache object is relocated.

Trait Implementations

impl Clone for MappingSource

fn clone(&self) -> MappingSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MappingSource

impl Debug for MappingSource

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

impl Eq for MappingSource

impl Hash for MappingSource

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,
