[][src]Type Definition uefi::proto::media::file::FileInfo

type FileInfo = NamedFileProtocolInfo<FileInfoHeader>;

Generic file information

The following rules apply when using this struct with set_info():

  • On directories, the file size is determined by the contents of the directory and cannot be changed by setting file_size. This member is ignored by set_info().
  • The physical_size is determined by the file_size and cannot be changed. This member is ignored by set_info().
  • The FileAttribute::DIRECTORY bit cannot be changed. It must match the file’s actual type.
  • A value of zero in create_time, last_access, or modification_time causes the fields to be ignored (and not updated).
  • It is forbidden to change the name of a file to the name of another existing file in the same directory.
  • If a file is read-only, the only allowed change is to remove the read-only attribute. Other changes must be carried out in a separate transaction.

Implementations

impl FileInfo[src]

pub fn new<'buf>(
    storage: &'buf mut [u8],
    file_size: u64,
    physical_size: u64,
    create_time: Time,
    last_access_time: Time,
    modification_time: Time,
    attribute: FileAttribute,
    file_name: &str
) -> Result<&'buf mut Self, FileInfoCreationError>
[src]

Create a FileInfo structure

The structure will be created in-place within the provided storage buffer. The buffer must be large enough to hold the data structure, including a null-terminated UCS-2 version of the name string.

The buffer must be correctly aligned. You can query the required alignment using the alignment() method of the Align trait that this struct implements.

pub fn file_size(&self) -> u64[src]

File size (number of bytes stored in the file)

pub fn physical_size(&self) -> u64[src]

Physical space consumed by the file on the file system volume

pub fn create_time(&self) -> &Time[src]

Time when the file was created

pub fn last_access_time(&self) -> &Time[src]

Time when the file was last accessed

pub fn modification_time(&self) -> &Time[src]

Time when the file's contents were last modified

pub fn attribute(&self) -> FileAttribute[src]

Attribute bits for the file

pub fn file_name(&self) -> &CStr16[src]

Name of the file
