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 = Table::new(); let mut ctx = WasiCtx::new(random, clocks, sched, table); ctx.set_stdin(Box::new(stdin.clone()));
Implementations
Create a new pipe from a Read
type.
All Handle
read operations delegate to reading from this underlying reader.
Create a new pipe from a shareable Read
type.
All Handle
read operations delegate to reading from this underlying reader.
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.
