Struct ExtentDataRef

Source
#[repr(C, packed(1))]
pub struct ExtentDataRef { pub root: U64<LE>, pub objectid: U64<LE>, pub offset: U64<LE>, pub count: U32<LE>, }
Expand description

Contains an indirect back reference for a file data extent.

Immediately follows an ExtentInlineRef. See that documentation for more details.

Fields§

§root: U64<LE>

The object ID for the file tree that references this extent.

§objectid: U64<LE>

The object ID of the inode that contains the extent data that references this extent.

§offset: U64<LE>

The offset within the file that corresponds to this extent.

§count: U32<LE>

The reference count being held.
