Enum LockKind 

pub enum LockKind {
    Optimistic,
    WriterExclusive,
    FullyExclusive,
}

Types of locks that can be acquired on the filter

Variants

Optimistic

Optimistic version tracking - does not block other operations but captures a version number to detect if data changed during the operation

WriterExclusive

Exclusive among writers only - prevents other writers but allows concurrent readers

FullyExclusive

Fully exclusive access - blocks all other operations (used only during evictions)

Trait Implementations

impl PartialEq for LockKind

fn eq(&self, other: &LockKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
