Functions

cfg_matches [
Experimental
]

Tests if a cfg-pattern matches the cfg set
contains_feature_attr [

Experimental
]
eval_condition [
Experimental
]

Evaluate a cfg-like condition (with any and all), using eval to evaluate individual items.
find_by_name [
Experimental
]
find_crate_name [
Experimental
]
find_deprecation [
Experimental
]

Find the deprecation attribute. None if none exists.
find_inline_attr [
Experimental
]

Determine what #[inline] attribute is present in attrs, if any.
find_repr_attrs [
Experimental
]

Parse #[repr(...)] forms.
find_stability [
Experimental
]

Find the first stability attribute. None if none exists.

mk_attr_id [
Experimental
]
mk_attr_inner [
Experimental
]

Returns an inner attribute with the given value.
