[−][src]Struct field_ref::EnumFieldRef
A OptionFieldRef references a field within an enum constant.
Implementations
impl<E, T> EnumFieldRef<E, T>[src]
pub fn new(
extractor: fn(_: &E) -> Option<&T>,
mut_extractor: fn(_: &mut E) -> Option<&mut T>
) -> Self[src]
extractor: fn(_: &E) -> Option<&T>,
mut_extractor: fn(_: &mut E) -> Option<&mut T>
) -> Self
Creates a new EnumFieldRef from a field extracting function and a mutable field extracting function.
