qwutils (WIP)

rust use qwutils::*;

Impls

rust Option { fn with(&self, |&T|->R) -> R; //short for as_ref().map() fn with_if(&self, &Option<U>, |&T,&U|->R) -> R; fn add/sub/mul/div_to(&self, &V); } bool { fn map(&self,||->R) -> R; //map_or, map_or_else also available fn option(&self) -> Option<()>; fn result(&self) -> Result<(),()>; //more bool impls: https://crates.io/crates/boolinator } Array/Tuple { [T; N]::to_tuple(self) -> (T, ...); (T, ...)::to_array(self) -> [T; N]; } Vec { fn push_option(&mut self, o: Option<T>); fn grow_to_with(&mut self, len, ||->T); fn grow_to(&mut self, len, T) where T: Clone; fn grow_to_default(&mut self, len) where T: Default; } Result { fn expect_nodebug(&self, &str); //for T without Debug //expect_err, unwrap, unwrap_err also available } Range { fn len(&self) -> T where T: Sub<T>; } For most functions _mut variants are available

Traits

RefClonable

rust trait RefClonable { fn refc(&self) -> Self; }

• Fast reference cloning
• Similar to Clone
• Implemented for Rc/Arc
• refcounted.refc() behaves like Rc/Arc::clone(&refcounted)

ScopedAccess (WIP)

rust trait ScopedAccess { fn access(&self, |&T|->R) -> R; fn access_mut(&mut self, |&mut T|->R) -> R; }

• Acces inner types which are only accessible scoped
• implemented for RefCell, RwLock, Rc/Arc, references, Box, ...

Functions

if_type (WIP)

rust pub fn if_type<T,Specific>(||->Specific) -> T; - calls the given function if T and Specific are the same type (by comparing TypeId) - Both Types must be statically known (T: 'static, Specific: 'static)
