#[repr(C, packed(1))]pub struct ExtentDataRef {
pub root: U64,
pub objectid: U64,
pub offset: U64,
pub count: U32,
}
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
The object ID for the file tree that references this extent.
objectid: U64
The object ID of the inode that contains the extent data that references this extent.
offset: U64
The offset within the file that corresponds to this extent.
count: U32
The reference count being held.
