630 | pub const ESPIPE: c_int = 29;

| ----------------------- similarly named constant `ESPIPE` defined here
|

help: a constant with a similar name exists

1125 - Err(err) if err.errno() == libc::ESTRPIPE => return try_resume(&stream.handle),
1125 + Err(err) if err.errno() == libc::ESPIPE => return try_resume(&stream.handle),
