Struct ExecutionModuleReadRequest 

pub struct ExecutionModuleReadRequest {
    pub taskid: u64,
    pub sha256: Vec<u8>,
    pub offset: u64,
    pub size: u64,
}

ExecutionModuleReadRequest asks the host for a module’s bytes from offset, at most size of them. The request never passes the module’s end and asks for at most 1 MiB. The Ark keeps one module request in flight per task. Each request gets 30s; an unanswered one fails the task.

Fields

taskid: u64

Task id whose module the Ark needs

sha256: Vec<u8>

Module’s SHA-256 digest, exactly 32 bytes

offset: u64

Byte offset within the module

size: u64

Most bytes to return, at most 1 MiB
