Struct FnScope

pub struct FnScope { /* private fields */ }

Expand description

RAII guard publishing scriptname and lineno for the body of a Rust compsys port, mirroring doshfunc’s scriptname save/set/restore and execlist’s lineno save/restore.

Implementations§

Source §

impl FnScope

Source

pub fn enter(name: &str) -> Self

scriptname = dupstring(name) (Src/exec.c:5963) plus oldlineno = lineno (Src/exec.c:1429), remembering the caller’s values for Drop.

Trait Implementations§

Source §

impl Drop for FnScope

Source §

fn drop(&mut self)

scriptname = funcsave->scriptname (Src/exec.c:6124) and lineno = oldlineno (Src/exec.c:1696).

Source §

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. Read more
