Struct simple_triple_buffer::Writer

pub struct Writer<T> { /* fields omitted */ }

Write side of the triple buffer.

Implementations

impl<T> Writer<T>

pub fn write_new(&mut self, write_op: impl FnMut(&T, &mut T))

Write the next state into the buffer.

The closure takes two arguments:

• The first is a reference to the previous state.
• The second is a mutable reference to some unspecified T value that should be overwritten with the new state.

The Reader is not blocked while this function runs. It is possible for multiple independent reads to happen while a single write is in process.

Example

let (mut writer, mut reader) = simple_triple_buffer::new_clone(0);
writer.write_new(|old, new| *new = *old + 1);
assert_eq!(*reader.read_newest(), 1);
