Struct LengthCalculatingWriter

pub struct LengthCalculatingWriter(pub usize);

Expand description

Writer that only tracks the amount of data written - useful if you need to calculate the length of some data when serialized but don’t yet need the full data.

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