PreparedLaneLock

orbit_core::shm

Struct PreparedLaneLock 

Source 
pub struct PreparedLaneLock { /* private fields */ }
Expand description

A lane lock prepared at opening, with no path construction or file open during acquisition. Each opener owns a distinct file description. Open after fork; inherited instances cannot be used by the child.

Implementations§
