Struct MappingInfo 

pub struct MappingInfo {
    pub mapped_bytes: usize,
    pub prefaulted: bool,
    pub hugetlbfs_backing: bool,
    pub backing_hugepage_bytes: Option<usize>,
}

Describes the OS-facing properties of a mapped backing region.

Fields

mapped_bytes: usize

Total mapped bytes for the region.

prefaulted: bool

Whether the mapping was prefaulted by touching each mapped page after mmap.

hugetlbfs_backing: bool

Whether the backing path resides on hugetlbfs.

backing_hugepage_bytes: Option<usize>

Hugepage size used by the backing filesystem when known.

Trait Implementations

impl Clone for MappingInfo

fn clone(&self) -> MappingInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MappingInfo

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

Formats the value using the given formatter.

impl PartialEq for MappingInfo

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