Struct PipeInner 

struct PipeInner {
    buf: [u8; 4096],
    read_pos: usize,
    write_pos: usize,
    len: usize,
    read_closed: bool,
    write_closed: bool,
    read_refs: usize,
    write_refs: usize,
}

Shared state for one pipe instance.

Fields

buf: [u8; 4096]

read_pos: usize

write_pos: usize

len: usize

Number of bytes currently buffered.

read_closed: bool

write_closed: bool

read_refs: usize

Number of open file-descriptions referencing the read end. The end is marked closed only when this reaches zero.

write_refs: usize

Number of open file-descriptions referencing the write end.
