Struct ManagedRole 

pub struct ManagedRole<R> { /* private fields */ }

Shared language-neutral arena, node, edge, and retention building blocks. Caller-owned role evidence kept separate from managed graph identity.

Changing a role cannot allocate, remove, renumber, or reorder an edge. The role type is intentionally generic so guests may use open role vocabularies without introducing a global enum in the managed-graph substrate.

Implementations

impl<R> ManagedRole<R>

pub const fn new(role: R) -> ManagedRole<R>

Wraps caller-owned role evidence.

pub const fn role(&self) -> &R

Borrows the current role.

pub fn replace_role(&mut self, role: R) -> R

Replaces the role and returns the previous evidence.
