Struct pal::ScopeExit

source · 
pub struct ScopeExit<F: FnOnce()> { /* private fields */ }
Expand description

Runs a closure when the instance goes out of scope.

Implementations§

source§

impl<F: FnOnce()> ScopeExit<F>

source

pub fn new(func: F) -> Self

Creates a new ScopeExit.

source

pub fn dismiss(self)

Prevents the closure from running when the instance goes out of scope.

This function takes ownership so that any variables borrowed by the closure will be usable again after calling cancel.
