Enum LogReplayPolicy 

pub enum LogReplayPolicy {
    Require,
    Auto,
    InMemoryOnReadOnly,
    ReadOnlyNoReplay,
}

Log replay policy controlling how pending logs are handled on open.

Standard

MS-VHDX §2.3 + MS-VHDX-只读扩展标准 §4.

Variants

Require

If a replayable log exists, finish() returns crate::error::Error::LogReplayRequired. No implicit replay.

Standard: MS-VHDX-只读扩展标准 §4.1

Auto

Automatically replay the log during finish(). On read-only open, replay is done in memory only.

Standard: MS-VHDX-只读扩展标准 §4.2

InMemoryOnReadOnly

In-memory replay is allowed for read-only opens. Not valid for read-write opens.

Standard: MS-VHDX-只读扩展标准 §4.3

ReadOnlyNoReplay

Open read-only without replaying the log. Only structure-level reads are guaranteed consistent; payload data-plane reads may be inconsistent.

Standard: MS-VHDX-只读扩展标准 §4.4

Trait Implementations

impl Clone for LogReplayPolicy

fn clone(&self) -> LogReplayPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LogReplayPolicy

impl Debug for LogReplayPolicy

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

Formats the value using the given formatter.

impl Default for LogReplayPolicy

fn default() -> LogReplayPolicy

Returns the “default value” for a type.

impl Eq for LogReplayPolicy

impl PartialEq for LogReplayPolicy

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