Struct ExecutionOutputRequest 

pub struct ExecutionOutputRequest {
    pub taskid: u64,
    pub stream: i32,
    pub offset: u64,
    pub size: u64,
}

ExecutionOutputRequest reads the next piece of a released task’s output.

Each stream is read once and in order, in pieces of the size the host asks for. The Ark refuses a size of zero, or one whose answer would not fit a wire message. The task closes for the host once exec_result has answered and both streams are read to their end.

Fields

taskid: u64

Task id to read the output of

stream: i32

Stream to read

offset: u64

Bytes of the stream read so far, the only offset the Ark accepts

size: u64

Most bytes to return, chosen by the host
