fn get_esplora_url(server_url: SafeUrl) -> Result<String>Expand description
When a port is specified in the Esplora URL, the esplora client inside LDK
node cannot connect to the lightning node when there is a trailing slash.
The SafeUrl::Display function will always serialize the SafeUrl with a
trailing slash, which causes the connection to fail.
To handle this, we explicitly construct the esplora URL when a port is specified.
