pub struct NodeDebugInfo {
    pub tag: BorTag,
    pub name: Option<String>,
    pub history: History,
}
Expand description

Some information that is irrelevant for the algorithm but very convenient to know about a tag for debugging and testing.

Fields§

§tag: BorTag

The tag in question.

§name: Option<String>

Name(s) that were associated with this tag (comma-separated). Typically the name of the variable holding the corresponding pointer in the source code. Helps match tag numbers to human-readable names.

§history: History

Notable events in the history of this tag, used for diagnostics.

NOTE: by virtue of being part of NodeDebugInfo, the history is automatically cleaned up by the GC. NOTE: this is !Send, it needs to be converted before displaying the actual diagnostics because src/diagnostics.rs requires Send.

Implementations§

source§

impl NodeDebugInfo

source

pub fn new(tag: BorTag, initial: Permission, span: Span) -> Self

Information for a new node. By default it has no name and an empty history.

source

pub fn add_name(&mut self, name: &str)

Add a name to the tag. If a same tag is associated to several pointers, it can have several names which will be separated by commas.
