Implementations

impl ObjectKeyV43

pub fn object(object_id: u64) -> Self

Creates a generic ObjectKey.

pub fn keys(object_id: u64) -> Self

Creates an ObjectKey for encryption keys.

pub fn attribute(object_id: u64, attribute_id: u64, key: AttributeKey) -> Self

Creates an ObjectKey for an attribute.

pub fn extent(object_id: u64, attribute_id: u64, range: Range<u64>) -> Self

Creates an ObjectKey for an extent.

pub fn from_extent(object_id: u64, attribute_id: u64, extent: ExtentKey) -> Self

Creates an ObjectKey from an extent.

pub fn child(object_id: u64, name: &str, casefold: bool) -> Self

Creates an ObjectKey for a child.

pub fn encrypted_child(object_id: u64, name: Vec<u8>, hash_code: u32) -> Self

Creates an ObjectKey for an encrypted child.

The hash_code is important here – especially for fscrypt as it affects the name of locked files.

For case-insensitive lookups in large encrypted directories, we lose the ability to binary search for an entry of interest because encryption breaks our sort order. In these cases we prefix records with a 32-bit hash based on the stable casefolded name. Hash collisions aside, this lets us jump straight to the entry of interest, if it exists.

pub fn graveyard_entry(graveyard_object_id: u64, object_id: u64) -> Self

Creates a graveyard entry for an object.

pub fn graveyard_attribute_entry( graveyard_object_id: u64, object_id: u64, attribute_id: u64, ) -> Self

Creates a graveyard entry for an attribute.

pub fn project_limit(object_id: u64, project_id: u64) -> Self

Creates an ObjectKey for a ProjectLimit entry.

pub fn project_usage(object_id: u64, project_id: u64) -> Self

Creates an ObjectKey for a ProjectUsage entry.

pub fn extended_attribute(object_id: u64, name: Vec<u8>) -> Self

pub fn key_for_merge_into(&self) -> Self

Returns the merge key for this key; that is, a key which is <= this key and any other possibly overlapping key, under Ord. This would be used for the hint in |merge_into|.

Trait Implementations

impl Clone for ObjectKeyV43
