Struct ToTLVBuilder 

pub struct ToTLVBuilder<P, T> { /* private fields */ }

The ToTLVBuilder is a helper struct that allows for an ergonomic writing of a TLV type that implements the ToTLV trait into a TLVWrite implementation.

This implementation is useful when the T type implements ToTLV.

Note that this implementation should be avoided when T has a large size, as it needs the T instance to be materialized prior to writing into the TLV.

Implementations

impl<P, T> ToTLVBuilder<P, T>

where P: TLVBuilderParent, T: ToTLV + 'static,

pub fn new(parent: P, tag: &TLVTag) -> ToTLVBuilder<P, T>

Create a new ToTLVBuilder for the given parent.

pub fn set(self, tlv: &T) -> Result<P, Error>

where T: Debug,

Write the TLV type into the writer.
