Function open_intent_sink 

pub fn open_intent_sink(
    intent: &KeyLogIntent,
) -> Result<Option<Arc<dyn KeyLogSink>>, Box<dyn Error + Send + Sync>>

Available on crate feature net only.

Resolve a KeyLogIntent into a concrete sink, opening files as needed.

• KeyLogIntent::Disabled and an unset SSLKEYLOGFILE on KeyLogIntent::Environment both return Ok(None).
• KeyLogIntent::File opens the path via FileKeyLogSink::try_open (cached + dedup’d by path).
• KeyLogIntent::Custom returns the supplied sink unchanged.
