Struct AliasData 

#[non_exhaustive]
pub struct AliasData {
    pub anchor: String,
    pub index: i32,
    pub mark: Mark,
}

This structure holds aliases data.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

anchor: String

The anchor.

index: i32

The node id.

mark: Mark

The anchor mark.
