Struct Mode

pub struct Mode(/* private fields */);

The kind of file of an entry.

Implementations

impl Mode

pub fn is_sparse(&self) -> bool

Return true if this is a sparse entry, as it points to a directory which usually isn’t what an ‘unsparse’ index tracks.

pub fn is_submodule(&self) -> bool

Return true if this is a submodule entry.

pub fn to_tree_entry_mode(&self) -> Option<EntryMode>

Convert this instance to a tree’s entry mode, or return None if for some and unexpected reason the bitflags don’t resemble any known entry-mode.

pub fn change_to_match_fs( self, stat: &Metadata, has_symlinks: bool, executable_bit: bool, ) -> Option<Change>

Compares this mode to the file system version (std::fs::symlink_metadata) and returns the change needed to update this mode to match the file.

• if has_symlinks is false symlink entries will simply check if there is a normal file on disk
• if executable_bit is false the executable bit will not be compared Change::ExecutableBit will never be generated

If there is a type change then we will use whatever information is present on the FS. Specifically if has_symlinks is false we will never generate Change::TypeChange { new_mode: Mode::SYMLINK }. and iff executable_bit is false we will never generate Change::TypeChange { new_mode: Mode::FILE_EXECUTABLE } (all files are assumed to be not executable). That measn that unstaging and staging files can be a lossy operation on such file systems.

If a directory replaced a normal file/symlink we assume that the directory is a submodule. Normal (non-submodule) directories would cause a file to be deleted from the index and should be handled before calling this function.

If the stat information belongs to something other than a normal file/ directory (like a socket) we just return an identity change (non-files can not be committed to git).

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

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl Mode

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

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

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

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
