Module rustc_monomorphize::polymorphize
source ยท Expand description
ยงPolymorphization Analysis
This module implements an analysis of functions, methods and closures to determine which generic parameters are unused (and eventually, in what ways generic parameters are used - only for their size, offset of a field, etc.).
Structsยง
- Visitor used to aggregate generic parameter uses.
Functionsยง
- Emit errors for the function annotated by
#[rustc_polymorphize_error]
, labelling each generic parameter which was unused. - Some parameters are considered used-by-default, such as non-generic parameters and the dummy generic parameters from closures, this function marks them as used.
