Struct NtfsFileName

pub struct NtfsFileName { /* private fields */ }

Structure of a $FILE_NAME attribute.

NTFS creates a $FILE_NAME attribute for every hard link. Its valuable information is the actual file name and whether this file represents a directory. Apart from that, it duplicates several fields of $STANDARD_INFORMATION, but these are only updated when the file name changes. You usually want to use the corresponding fields from NtfsStandardInformation instead.

A $FILE_NAME attribute can be resident or non-resident.

Implementations

impl NtfsFileName

pub fn access_time(&self) -> NtfsTime

Returns the last access time stored in this $FILE_NAME record.

Note that NTFS only updates it when the file name is changed! Check NtfsStandardInformation::access_time for a last access time that is always up to date.

pub fn allocated_size(&self) -> u64

Returns the allocated size of the file data, in bytes. “Data” refers to the unnamed $DATA attribute only. Other $DATA attributes are not considered.

Note that NTFS only updates it when the file name is changed! If you need an always up-to-date allocated size, use NtfsFile::data to get the unnamed $DATA attribute, fetch the corresponding NtfsAttribute, and use NtfsAttribute::value to fetch the corresponding NtfsAttributeValue. For non-resident attribute values, you now need to walk through each Data Run and sum up the return values of NtfsDataRun::allocated_size. For resident attribute values, the length equals the allocated size.

pub fn creation_time(&self) -> NtfsTime

Returns the creation time stored in this $FILE_NAME record.

Note that NTFS only updates it when the file name is changed! Check NtfsStandardInformation::creation_time for a creation time that is always up to date.

pub fn data_size(&self) -> u64

Returns the size actually used by the file data, in bytes.

“Data” refers to the unnamed $DATA attribute only. Other $DATA attributes are not considered.

This is less or equal than NtfsFileName::allocated_size.

Note that NTFS only updates it when the file name is changed! If you need an always up-to-date size, use NtfsFile::data to get the unnamed $DATA attribute, fetch the corresponding NtfsAttribute, and use NtfsAttribute::value to fetch the corresponding NtfsAttributeValue. Then query NtfsAttributeValue::len.

pub fn file_attributes(&self) -> NtfsFileAttributeFlags

Returns flags that a user can set for a file (Read-Only, Hidden, System, Archive, etc.). Commonly called “File Attributes” in Windows Explorer.

Note that NTFS only updates it when the file name is changed! Check NtfsStandardInformation::file_attributes for file attributes that are always up to date.

pub fn is_directory(&self) -> bool

Returns whether this file is a directory.

pub fn mft_record_modification_time(&self) -> NtfsTime

Returns the MFT record modification time stored in this $FILE_NAME record.

Note that NTFS only updates it when the file name is changed! Check NtfsStandardInformation::mft_record_modification_time for an MFT record modification time that is always up to date.

pub fn modification_time(&self) -> NtfsTime

Returns the modification time stored in this $FILE_NAME record.

Note that NTFS only updates it when the file name is changed! Check NtfsStandardInformation::modification_time for a modification time that is always up to date.

pub fn name(&self) -> U16StrLe<'_>

Gets the file name and returns it wrapped in a U16StrLe.

pub fn name_length(&self) -> usize

Returns the file name length, in bytes.

A file name has a maximum length of 255 UTF-16 code points (510 bytes).

pub fn namespace(&self) -> NtfsFileNamespace

Returns the NtfsFileNamespace of this file name.

pub fn parent_directory_reference(&self) -> NtfsFileReference

Returns an NtfsFileReference for the directory where this file is located.
