Enum AccessPattern 

pub enum AccessPattern {
    Normal,
    Sequential,
    Random,
    WillNeedOnce,
}

Access pattern hint for memory-mapped regions.

These hints inform the kernel’s readahead and caching strategies.

Variants

Normal

Normal access pattern (kernel default behavior).

Sequential

Sequential access - kernel will aggressively readahead. Use for full scans, sequential iteration, compaction.

Random

Random access - kernel will minimize readahead. Use for point lookups, B-tree traversal.

WillNeedOnce

Pages will be accessed only once then not needed. Kernel may deprioritize caching.

Trait Implementations

impl Clone for AccessPattern

fn clone(&self) -> AccessPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccessPattern

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

Formats the value using the given formatter.

impl Default for AccessPattern

fn default() -> AccessPattern

Returns the “default value” for a type.

impl PartialEq for AccessPattern

fn eq(&self, other: &AccessPattern) -> 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.
