Struct breez_sdk_core::lightning::util::ser::FixedLengthReader

pub struct FixedLengthReader<R>
where R: Read,
{ /* private fields */ }
Expand description

Essentially std::io::Take but a bit simpler and with a method to walk the underlying stream forward to ensure we always consume exactly the fixed length specified.

This is not exported to bindings users as manual TLV building is not currently supported in bindings
