OpaqueBorrow

facet_core

Struct OpaqueBorrow 

Source 
#[repr(transparent)]
pub struct OpaqueBorrow<'facet, T>(pub T, _);
Expand description

Lifetime-aware wrapper used for field-level #[facet(opaque)].

This lets derive-generated shapes describe borrowed opaque fields without requiring 'static, while still tying the wrapper to the active Facet lifetime.
