Struct Extent 

pub struct Extent {
    pub logical: u64,
    pub physical: u64,
    pub length: u64,
    pub flags: ExtentFlags,
}

A single extent in a file’s physical block mapping.

Each extent represents a contiguous range of physical blocks that store a portion of the file’s data.

Fields

logical: u64

Logical offset in the file where this extent starts (in bytes).

physical: u64

Physical offset on the block device where this extent starts (in bytes).

length: u64

Length of this extent (in bytes).

flags: ExtentFlags

Flags describing this extent’s properties.

Implementations

impl FiemapExtent

pub fn is_last(&self) -> bool

Returns true if this is the last extent in the file.

pub fn is_shared(&self) -> bool

Returns true if the extent is shared with other files.

pub fn is_unwritten(&self) -> bool

Returns true if the extent represents unwritten/preallocated space.

Trait Implementations

impl Clone for FiemapExtent

fn clone(&self) -> FiemapExtent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FiemapExtent

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

Formats the value using the given formatter.

impl Display for FiemapExtent

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

Formats the value using the given formatter.

impl PartialEq for FiemapExtent

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