Struct AttrInfo

pub struct AttrInfo {
    pub attributes: Vec<Attribute>,
    pub inline: Option<InlineAttr>,
    pub rename: Option<String>,
    pub public: bool,
}

Information about the attributes and visibility of an item, field or variant..

Fields

attributes: Vec<Attribute>

Attributes (#[...]).

inline: Option<InlineAttr>

Inline hints (on functions only).

rename: Option<String>

The name computed from charon::rename and charon::variants_prefix attributes, if any. This provides a custom name that can be used by consumers of llbc. E.g. Aeneas uses this to rename definitions in the extracted code.

public: bool

Whether this item is declared public. Impl blocks and closures don’t have visibility modifiers; we arbitrarily set this to false for them.

Note that this is different from being part of the crate’s public API: to be part of the public API, an item has to also be reachable from public items in the crate root. For example:

mod foo {
    pub struct X;
}
mod bar {
    pub fn something(_x: super::foo::X) {}
}
pub use bar::something; // exposes `X`

Without the pub use ..., neither X nor something would be part of the crate’s public API (this is called “pub-in-priv” items). With or without the pub use, we set public = true; computing item reachability is harder.
