Macro repr_offset::off [−][src]
Gets the FieldOffset
for a (possibly nested) field, and an optionally passed in value.
The value argument is only necessary when the type that the fields are from can't be inferred.
Example
use repr_offset::{ for_examples::ReprC, off, FieldOffset, ROExtAcc, }; let this = ReprC {a: 3u8, b: 5u8, c: 8u8, d: 13u8}; // The value must be passed to the macro when you want to call // any method on the returned `FieldOffset`. assert_eq!(off!(this; a).get(&this), &this.a); assert_eq!(this.f_get(off!(this; b)), &this.b); assert_eq!(this.f_get(off!(c)), &this.c); assert_eq!(this.f_get(off!(d)), &this.d);
