Struct rustc_feature::AttributeTemplate
source · pub struct AttributeTemplate {
pub word: bool,
pub list: Option<&'static str>,
pub name_value_str: Option<&'static str>,
}
Expand description
A template that the attribute input must match.
Only top-level shape (#[attr]
vs #[attr(...)]
vs #[attr = ...]
) is considered now.
Fields§
§word: bool
If true
, the attribute is allowed to be a bare word like #[test]
.
list: Option<&'static str>
If Some
, the attribute is allowed to take a list of items like #[allow(..)]
.
name_value_str: Option<&'static str>
If Some
, the attribute is allowed to be a name/value pair where the
value is a string, like #[must_use = "reason"]
.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
