Struct libp2p_wasm_ext::Connection

source · [−]

pub struct Connection { /* private fields */ }

Expand description

Active stream of data with a remote.

It is guaranteed that each call to io::Write::write on this object maps to exactly one call to write on the FFI. In other words, no internal buffering happens for writes, and data can’t be split.
