Struct Reader 

pub struct Reader<T>
where
    T: AnyBitPattern,
{ /* private fields */ }

A reading handle of a SeqLock.

Cheap to clone: multiple readers may share the same lock. Reader is both Send and Sync; concurrent reads do not interfere because the underlying validation protocol is wait-free for readers in the absence of a concurrent writer and lock-free in its presence.

Implementations

impl<T> Reader<T>

where T: AnyBitPattern,

pub fn read(&self) -> T

Reads the latest stable value.

Spin-loops while the writer is mid-write or while a torn read is observed; returns once a consistent value has been observed.

Examples

use low_latency_data_structures::seqlock::new;

let (writer, reader) = new(0u64);
writer.write(42);
assert_eq!(reader.read(), 42);

Trait Implementations

impl<T> Clone for Reader<T>

where T: AnyBitPattern,

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for Reader<T>

where T: AnyBitPattern,

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

Formats the value using the given formatter.
