Struct Log 

Source 
pub struct Log<'a> { /* private fields */ }
Expand description

View into the VHDX log ring buffer.

The log is a circular buffer stored contiguously at a location specified in the VHDX header. It consists of variable-sized entries that are at least 4 KB aligned.

Implementations§

Source§

impl<'a> Log<'a>

Source

pub fn entry(&self, index: usize) -> Result<Entry<'_>>

Get a log entry by index (0-based, scanning from the start of the buffer).

Entries are located by walking the buffer: entry 0 starts at offset 0, entry 1 starts at entry0.header().entry_length() bytes from the start, etc.

§Errors

Returns an error if the index is out of bounds or an entry is malformed.

Source

pub fn entries(&self) -> impl Iterator<Item = Entry<'_>> + '_

Iterate over all valid log entries in the buffer.

Scans entries sequentially from the beginning. Stops when the buffer is exhausted or an invalid entry is encountered.
