Struct ModuleDownloadConfig 

Source 
pub struct ModuleDownloadConfig {
    pub range_timeout: Duration,
    pub max_module_size: u64,
}
Expand description

Tunables for a module pull.

Fields§

§range_timeout: Duration

Per-ASK timeout — the window any single transport call to a holder gets, whether it is a fetchModuleRange or the getModuleInfo handshake. A holder that does not answer within it is treated as a failed source for that ask and the next holder is tried.

It covers the descriptor ask as well as ranges because the descriptor phase’s worst-case wait (MAX_DESCRIPTOR_ATTEMPTS × holders × this window) has to be enforceable by this crate; a transport whose get_module_info never resolves otherwise holds a pull open forever. The name is kept for compatibility — renaming a public field is a breaking change, and a truthful bound is worth more than a tidier name.

§max_module_size: u64

Upper bound on the total_size a ModuleInfo may declare. The descriptor comes from an UNTRUSTED holder and sizes the bytes this node will STAGE on disk before either final gate can reject it, so it is refused above this bound before a single range is fetched. It is a disk policy knob, not a memory bound — see DEFAULT_MAX_MODULE_SIZE. Defaults to DEFAULT_MAX_MODULE_SIZE.
