Struct SharedDataRef

#[repr(C, packed(1))]
pub struct SharedDataRef {
    pub count: U32<LE>,
}

This structure contains the reference count for a shared back reference for a file data extent.

This immediately follows an ExtentInlineRef of type SharedDataRef inside an extent item.

Fields

count: U32<LE>

The reference count.
