Struct wasi_common::pipe::ReadPipe [−][src]
pub struct ReadPipe<R: Read> { /* fields omitted */ }
Expand description
A virtual pipe read end.
A variety of From
impls are provided so that common pipe types are easy to create. For example:
use wasi_common::{pipe::ReadPipe, WasiCtx, Table}; let stdin = ReadPipe::from("hello from stdin!"); // Brint these instances from elsewhere (e.g. wasi-cap-std-sync): let random = todo!(); let clocks = todo!(); let sched = todo!(); let table = Rc::new(RefCell::new(Table::new())); let ctx = WasiCtx::builder(random, clocks, sched, table) .stdin(Box::new(stdin.clone())) .build();
Implementations
impl<R: Read> ReadPipe<R>
[src]
impl<R: Read> ReadPipe<R>
[src]pub fn new(r: R) -> Self
[src]
pub fn new(r: R) -> Self
[src]Create a new pipe from a Read
type.
All Handle
read operations delegate to reading from this underlying reader.
pub fn from_shared(reader: Arc<RwLock<R>>) -> Self
[src]
pub fn from_shared(reader: Arc<RwLock<R>>) -> Self
[src]Create a new pipe from a shareable Read
type.
All Handle
read operations delegate to reading from this underlying reader.
pub fn try_into_inner(self) -> Result<R, Self>
[src]
pub fn try_into_inner(self) -> Result<R, Self>
[src]Try to convert this ReadPipe<R>
back to the underlying R
type.
This will fail with Err(self)
if multiple references to the underlying R
exist.
