RwWriteGuard.init
pub init(Source: mut Self&&)Transfers unlock authority within the same thread. Source: Guard left inert.
RwWriteGuard.operator
pub fn operator =(Source: readonly Self&) -> void = delete;Rejects copying unlock authority. Source: Existing guard. Return: No runtime result; this assignment is deleted and cannot be invoked.

pub fn operator =(Source: mut Self&&) -> void = delete;Rejects replacement of an active guard; use a new scoped guard instead. Source: Transfer source. Return: No runtime result; this assignment is deleted and cannot be invoked.
RwWriteGuard.IsEmpty
pub IsEmpty: bool;Observes moved/inert guard state.
RwWriteGuard.Value
pub readonly fn Value() -> readonly T&Borrows protected payload readonly until this guard is moved/unlocked/destroyed. Return: Readonly reference; moved guard access traps.
RwWriteGuard.Value
pub fn Value() -> mut T&Borrows protected payload writable under exclusive access. Return: Writable reference valid through this live guard.
