Struct MpMcQueue

Source 
pub struct MpMcQueue<T, const N: usize> { /* private fields */ }
Expand description

MPMC queue with a capacity for N elements N must be a power of 2 The max value of N is u8::MAX - 1 if mpmc_large feature is not enabled.

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.
