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]

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]

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]

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.
