Struct Mapping 

pub struct Mapping { /* private fields */ }

Describes a single memory mapping entry.

The size of this type heavily influences Starnix’s heap usage in common scenarios, please think twice about increasing its size. Compiling in “release” mode includes a compile time check for size increase.

Trait Implementations

impl Clone for Mapping

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mapping

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

Formats the value using the given formatter.

impl Drop for Mapping

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq for Mapping

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