Evgenii Stratonikov	971e740ea3	[#35 ] network: Use AppendComponent() for TLS encapsulation As advocated explicitly in https://github.com/multiformats/go-multiaddr/blob/master/v015-MIGRATION.md Answering a question about safety: AppendComponent() appends to `a.ma`` in place. `a.ma` is created by FromString() function, so there is only a single goroutine appending to it. Thus, assuming `FromString()` itself is called from a single goroutine, no data race is introduced. Signed-off-by: Evgenii Stratonikov <e.stratonikov@yadro.com>	2025-04-12 21:19:30 +03:00
