Struct parselnk::header::FileAttributeFlags
source · [−]pub struct FileAttributeFlags { /* private fields */ }
Expand description
The FileAttributesFlags structure defines bits that specify the file attributes of the link target, if the target is a file system item. File attributes can be used if the link target is not available, or if accessing the target would be inefficient. It is possible for the target items attributes to be out of sync with this value.
Implementations
The file or directory is read-only. For a file, if this bit is set, applications can read the file but cannot write to it or delete it. For a directory, if this bit is set, applications cannot delete the directory.
The file or directory is hidden. If this bit is set, the file or folder is not included in an ordinary directory listing.
The file or directory is part of the operating system or is used exclusively by the operating system.
A bit that MUST be zero.
The link target is a directory instead of a file.
The file or directory is an archive file. Applications use this flag to mark files for backup or removal.
A bit that MUST be zero.
The file or directory has no other flags set. If this bit is 1, all other bits in this structure MUST be clear.
The file is being used for temporary storage.
The file is a sparse file.
The file or directory has an associated reparse point.
The file or directory is compressed. For a file, this means that all data in the file is compressed. For a directory, this means that compression is the default for newly created files and subdirectories.
The data of the file is not immediately available.
The contents of the file need to be indexed.
The file or directory is encrypted. For a file, this means that all data in the file is encrypted. For a directory, this means that encryption is the default for newly created files and subdirectories.
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
Safety
The caller of the bitflags!
macro can chose to allow or
disallow extra bits for their bitflags type.
The caller of from_bits_unchecked()
has to ensure that
all bits correspond to a defined flag or that extra bits
are valid for this bitflags type.
Returns true
if there are flags common to both self
and other
.
Returns true
if all of the flags in other
are contained within self
.
Inserts or removes the specified flags depending on the passed value.
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
.
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
.
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
.
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
.
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
.
