Implementations

impl<T> IterVTableBuilder<T>

where T: IterItem,

pub const fn new() -> IterVTableBuilder<T>

Creates a new IterVTableBuilder with all fields set to None.

pub const fn init_with_value( self, f: for<'value> unsafe fn(PtrConst<'value>) -> PtrMut<'value>, ) -> IterVTableBuilder<T>

Sets the init_with_value function

pub const fn next( self, f: for<'iter> unsafe fn(PtrMut<'iter>) -> Option<<T as IterItem>::Item<'iter>>, ) -> IterVTableBuilder<T>

Sets the next function

pub const fn next_back( self, f: for<'iter> unsafe fn(PtrMut<'iter>) -> Option<<T as IterItem>::Item<'iter>>, ) -> IterVTableBuilder<T>

Sets the next_back function

pub const fn dealloc( self, f: for<'iter> unsafe fn(PtrMut<'iter>), ) -> IterVTableBuilder<T>

Sets the dealloc function

pub const fn build(self) -> IterVTable<T>

Builds the IterVTable from the current state of the builder.

Panics

Panic if any of the required fields (init_with_value, next, dealloc) are None.
