Struct Mapping 

pub struct Mapping { /* private fields */ }

A mapped memory region

Just about the only interesting thing to do with this is to call .as_bytes() on it.

A Drop trait is implemented which calls munmap() when the Mapping goes out of scope.

Implementations

impl Mapping

pub fn as_bytes(&self) -> &[u8]

Gets a reference to the underlying memory as a &[u8].

For as long as this shared reference exists, Rust’s borrowing rules require that the memory must not change. For that reason, it’s only possible to construct a Mapping from an immutable file.

Trait Implementations

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: &Mapping) -> 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.
