Enum TryResult

pub enum TryResult<R> {
    Present(R),
    Absent,
    Locked,
}

Represents the result of a non-blocking read from a DashMap.

Variants

Present(R)

The value was present in the map, and the lock for the shard was successfully obtained.

Absent

The shard wasn’t locked, and the value wasn’t present in the map.

Locked

The shard was locked.

Implementations

impl<R> TryResult<R>

pub fn is_present(&self) -> bool

Returns true if the value was present in the map, and the lock for the shard was successfully obtained.

pub fn is_absent(&self) -> bool

Returns true if the shard wasn’t locked, and the value wasn’t present in the map.

pub fn is_locked(&self) -> bool

Returns true if the shard was locked.

pub fn unwrap(self) -> R

If self is Present, returns the reference to the value in the map. Panics if self is not Present.

pub fn try_unwrap(self) -> Option<R>

If self is Present, returns the reference to the value in the map. If self is not Present, returns None.

Trait Implementations

impl<R: Debug> Debug for TryResult<R>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
