Struct gix_index::entry::Flags

pub struct Flags(_);

In-memory flags.

Notably, not all of these will be persisted but can be used to aid all kinds of operations.

Implementations

impl Flags

pub const PATH_LEN: Self = _

The mask to obtain the length of the path associated with this entry, up to 4095 characters without extension.

pub const STAGE_MASK: Self = _

The mask to apply to obtain the stage number of an entry, encoding three value: 0 = base, 1 = ours, 2 = theirs.

pub const EXTENDED: Self = _

If set, additional bits need to be written to storage.

pub const ASSUME_VALID: Self = _

If set, the entry be assumed to match with the version on the working tree, as a way to avoid lstat() checks.

pub const UPDATE: Self = _

Indicates that an entry needs to be updated as it’s in-memory representation doesn’t match what’s on disk.

pub const REMOVE: Self = _

Indicates an entry should be removed - this typically happens during writing, by simply skipping over them.

pub const UPTODATE: Self = _

Indicates that an entry is known to be up-to-date.

pub const ADDED: Self = _

Only temporarily used by unpack_trees() (in C).

pub const HASHED: Self = _

Whether an up-to-date object hash exists for the entry.

pub const FSMONITOR_VALID: Self = _

Set if the filesystem monitor is valid.

pub const WORKTREE_REMOVE: Self = _

Remove in work directory

pub const CONFLICTED: Self = _

Set to indicate the entry exists in multiple stages at once due to conflicts.

pub const UNPACKED: Self = _

Indicates that the entry was already turned into a tree.

pub const NEW_SKIP_WORKTREE: Self = _

Only temporarily used by unpack_trees() (in C)

pub const PATHSPEC_MATCHED: Self = _

temporarily mark paths matched by a path spec

pub const UPDATE_IN_BASE: Self = _

When the index is split, this indicates the entry is up-to-date in the shared portion of the index.

pub const STRIP_NAME: Self = _

Indicates the entry name is present in the base/shared index, and thus doesn’t have to be stored in this one.

pub const INTENT_TO_ADD: Self = _

Created with git add --intent-to-add to mark empty entries that have their counter-part in the worktree, but not yet in the object database.

pub const SKIP_WORKTREE: Self = _

Stored at rest

pub const EXTENDED_2: Self = _

For future extension

impl Flags

pub const fn empty() -> Self

Returns an empty set of flags.

pub const fn all() -> Self

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub const fn from_bits(bits: u32) -> Option<Self>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> Self

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const fn from_bits_retain(bits: u32) -> Self

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub fn from_name(name: &str) -> Option<Self>

Get the value for a flag from its stringified name.

Names are case-sensitive, so must correspond exactly to the identifier given to the flag.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: Self) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: Self) -> bool

Returns true if all of the flags in other are contained within self.

pub fn insert(&mut self, other: Self)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: Self)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: Self)

Toggles the specified flags in-place.

pub fn set(&mut self, other: Self, value: bool)

Inserts or removes the specified flags depending on the passed value.

pub const fn intersection(self, other: Self) -> Self

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

pub const fn union(self, other: Self) -> Self

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

pub const fn difference(self, other: Self) -> Self

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

pub const fn symmetric_difference(self, other: Self) -> Self

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.

pub const fn complement(self) -> Self

Returns the complement of this set of flags.

Specifically, the returned set contains all the flags which are not set in self, but which are allowed for this type.

Alternatively, it can be thought of as the set difference between Self::all() and self (e.g. Self::all() - self)

This is equivalent to using the ! operator (e.g. ops::Not), as in !flags.

impl Flags

pub const fn iter(&self) -> Iter<Flags>

pub const fn iter_names(&self) -> IterNames<Flags>

Iterate over enabled flag values with their stringified names.

impl Flags

pub fn stage(&self) -> Stage

Return the stage as extracted from the bits of this instance.

pub fn to_storage(self) -> Flags

Transform ourselves to a storage representation to keep all flags which are to be persisted, skipping all extended flags. Note that the caller has to check for the EXTENDED bit to be present and write extended flags as well if so.
