Trait Implementations

impl AsRawFd for MemoryFile

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Borrow<MemoryFile> for NamedMemoryFile

fn borrow(&self) -> &MemoryFile

Immutably borrows from an owned value.

impl BorrowMut<MemoryFile> for NamedMemoryFile

fn borrow_mut(&mut self) -> &mut MemoryFile

Mutably borrows from an owned value.

impl Clone for MemoryFile

fn clone(&self) -> MemoryFile

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryFile

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

Formats the value using the given formatter.

impl From<MemoryFile> for File

fn from(from: MemoryFile) -> Self

Converts to this type from the input type.

impl From<MemoryFile> for ManagedFD

fn from(from: MemoryFile) -> Self

Converts to this type from the input type.

impl FromRawFd for MemoryFile

unsafe fn from_raw_fd(fd: RawFd) -> Self

Constructs a new instance of Self from the given raw file descriptor.

impl Hash for MemoryFile

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,

Feeds a slice of this type into the given Hasher.

impl IntoRawFd for MemoryFile

fn into_raw_fd(self) -> RawFd

Consumes this object, returning the raw underlying file descriptor.

impl Ord for MemoryFile

fn cmp(&self, other: &MemoryFile) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<MemoryFile> for MemoryFile

fn eq(&self, other: &MemoryFile) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<MemoryFile> for MemoryFile

fn partial_cmp(&self, other: &MemoryFile) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

const fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

const fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

const fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

const fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
