Struct ArcFileDescOpenerEnv 

pub struct ArcFileDescOpenerEnv<O> { /* private fields */ }

A FileDescOpener implementation which delegates to another implementation, but wraps any returned handles with in an Arc.

Implementations

impl<O> ArcFileDescOpenerEnv<O>

pub fn new(opener: O) -> Self

Create a new wrapper instance around some other FileDescOpener implementation.

Trait Implementations

impl<O: Clone> Clone for ArcFileDescOpenerEnv<O>

fn clone(&self) -> ArcFileDescOpenerEnv<O>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<O: Debug> Debug for ArcFileDescOpenerEnv<O>

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

Formats the value using the given formatter.

impl<O: Default> Default for ArcFileDescOpenerEnv<O>

fn default() -> ArcFileDescOpenerEnv<O>

Returns the “default value” for a type.

impl<O: FileDescOpener> FileDescOpener for ArcFileDescOpenerEnv<O>

type OpenedFileHandle = Arc<<O as FileDescOpener>::OpenedFileHandle>

A type which represents an opened file descriptor.

fn open_path( &mut self, path: &Path, opts: &OpenOptions, ) -> Result<Self::OpenedFileHandle>

Open a provided path with the specified OpenOptions.

fn open_pipe(&mut self) -> Result<Pipe<Self::OpenedFileHandle>>

Create a new Pipe pair.

impl<O: PartialEq> PartialEq for ArcFileDescOpenerEnv<O>

fn eq(&self, other: &ArcFileDescOpenerEnv<O>) -> 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.

impl<O: SubEnvironment> SubEnvironment for ArcFileDescOpenerEnv<O>

fn sub_env(&self) -> Self

Create a new sub-environment, which starts out idential to its parent, but any changes on the new environment will not be reflected on the parent.
