Struct ra_ap_rustc_data_structures::sync::FreezeLock

pub struct FreezeLock<T> { /* private fields */ }

A type which allows mutation using a lock until the value is frozen and can be accessed lock-free.

Unlike RwLock, it can be used to prevent mutation past a point.

Implementations

impl<T> FreezeLock<T>

pub fn new(value: T) -> Self

pub fn frozen(value: T) -> Self

pub fn with(value: T, frozen: bool) -> Self

pub fn clone(&self) -> Self

where T: Clone,

Clones the inner value along with the frozen state.

pub fn is_frozen(&self) -> bool

pub fn get(&self) -> Option<&T>

Get the inner value if frozen.

pub fn read(&self) -> FreezeReadGuard<'_, T>

pub fn borrow(&self) -> FreezeReadGuard<'_, T>

pub fn write(&self) -> FreezeWriteGuard<'_, T>

pub fn try_write(&self) -> Option<FreezeWriteGuard<'_, T>>

pub fn freeze(&self) -> &T

Trait Implementations

impl<T: Default> Default for FreezeLock<T>

fn default() -> FreezeLock<T>
