Enum gix_status::index_as_worktree::Change

pub enum Change<T = (), U = ()> {
    Removed,
    Type,
    Modification {
        executable_bit_changed: bool,

}

How an index entry needs to be changed to obtain the destination worktree state, i.e. entry.apply(this_change) == worktree-entry.

Variants

Removed

This corresponding file does not exist in the worktree anymore.

Type

The type of file changed compared to the worktree, i.e. a symlink s now a file.

Modification

This worktree file was modified in some form, like a permission change or content change or both, as compared to this entry.

Fields

executable_bit_changed: bool

Indicates that one of the stat changes was an executable bit change which is a significant change itself.

content_change: Option<T>

The output of the CompareBlobs run on this entry. If there is no content change and only the executable bit changed then this is None.

set_entry_stat_size_zero: bool

If true, the caller is expected to set entry.stat.size = 0 to assure this otherwise racily clean entry can still be detected as dirty next time this is called, but this time without reading it from disk to hash it. It’s a performance optimization and not doing so won’t change the correctness of the operation.

SubmoduleModification(U)

A submodule is initialized and checked out, and there was modification to either:

• the HEAD as compared to the superproject’s desired commit for HEAD
• the worktree has at least one modified file
• there is at least one untracked file

The exact nature of the modification is handled by the caller which may retain information per submodule or re-compute details as needed when seeing this variant.

Trait Implementations

impl<T: Clone, U: Clone> Clone for Change<T, U>

fn clone(&self) -> Change<T, U>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug, U: Debug> Debug for Change<T, U>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T, U> From<Change<T, U>> for EntryStatus<T, U>

fn from(value: Change<T, U>) -> Self

Converts to this type from the input type.

impl<T: Ord, U: Ord> Ord for Change<T, U>

fn cmp(&self, other: &Change<T, U>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<T: PartialEq, U: PartialEq> PartialEq for Change<T, U>

fn eq(&self, other: &Change<T, U>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: PartialOrd, U: PartialOrd> PartialOrd for Change<T, U>

fn partial_cmp(&self, other: &Change<T, U>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
