Enum FileExtentType 

pub enum FileExtentType {
    Inline,
    Regular,
    Prealloc,
    Unknown(u8),
}

File extent type.

Variants

Inline

Data stored directly in the tree leaf (small files or file tails).

Regular

Data stored in a separate disk extent, referenced by logical address.

Prealloc

Preallocated extent (reserved but not yet written).

Unknown(u8)

Unrecognized extent type byte.

Implementations

impl FileExtentType

pub fn from_raw(v: u8) -> Self

Convert a raw on-disk extent type byte to a FileExtentType variant.

pub fn name(&self) -> &'static str

Return the human-readable name of this extent type.

pub fn to_raw(self) -> u8

Convert back to the raw on-disk byte value.

Trait Implementations

impl Clone for FileExtentType

fn clone(&self) -> FileExtentType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileExtentType

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

Formats the value using the given formatter.

impl PartialEq for FileExtentType

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