Struct btrfs_no_std::ExtentInlineRef

#[repr(C, packed)]
pub struct ExtentInlineRef {
    pub type: u8,
    pub offset: U64<LE>,
}

This acts as a header for different types of inline extent back references inside extent or metadata items.

Fields

type: u8

The type of reference, which corresponds with a value from ExtentInlineRefType. This field also determines the semantic importance of offset.

offset: U64<LE>

This field has different functions depending on the value of type.
