Struct SinkGuard 

pub struct SinkGuard { /* private fields */ }

RAII handle that installs a custom sink and restores the prior one on drop. The TUI uses this so stderr emission resumes after the alt-screen exits in the normal-return path. Note: the workspace’s release profile sets panic = "abort", so on a release-build panic this Drop does not run — the panic hook (in [super::tui]) is what restores the terminal under abort, and stderr is owned by the alt-screen until then. Under the default unwind profile (dev/test), stack unwinding drops the guard normally.

Nested guards in nested scopes restore in reverse construction order so long as Rust’s normal stack-LIFO drop applies (no explicit mem::take of the field, no moves into a heap-owned container that delays drop). Don’t move the guard into Box/Arc/Vec and expect LIFO.

Implementations

impl SinkGuard

pub fn install(new_sink: Arc<dyn LogSink>) -> Self

Install new_sink as the active sink, capturing the prior one for restoration on drop.

Trait Implementations

impl Drop for SinkGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
