Struct EvalContextFrame 

pub struct EvalContextFrame { /* private fields */ }

RAII form of C’s execode context push/pop (Src/exec.c:1265-1266 and the matching zsh_eval_context[alen] = NULL at c:1281).

zshrs does not route every nested execution through execode, so the callers that C reaches via execode(prog, …, "label") push their label with this guard instead. Dropping it pops, on every return path including a panic — C relies on the plain assignment at c:1281 being reached, which the guard reproduces more robustly.

Implementations

impl EvalContextFrame

pub fn push(context: &str) -> Self

c:1265-1266 — zsh_eval_context[alen] = context;

Trait Implementations

impl Drop for EvalContextFrame

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.
