Struct FileAttributes

pub struct FileAttributes {
    pub file_type: FileType,
    pub unused_bit: bool,
    pub save_with_replace_flag: bool,
    pub locked_flag: bool,
    pub closed_flag: bool,
}

We introduce the term “file attributes” to refer to the full 8-bit directory entry field which contains the file type along with several flags.

Fields

file_type: FileType

Bits 0-3 indicate the file type.

unused_bit: bool

Bit 4 is unused, but we store it anyway so we can reproduce this field verbatim.

save_with_replace_flag: bool

Bit 5 is the “save with replace” flag.

locked_flag: bool

Bit 6 is the “locked” flag, indicated by a “>” in directory listings.

closed_flag: bool

Bit 7 is the “closed” flag. Files are normally closed, so this bit is normally set. Unclosed files are indicated in directory listings with a “*”, leading to such files being known as “splat files”.

Implementations

impl FileAttributes

pub fn from_byte(byte: u8) -> FileAttributes

Parse a byte into a FileAttributes struct.

pub fn to_byte(&self) -> u8

Generate the byte which encodes this FileAttributes struct.

pub fn is_scratched(&self) -> bool

Return true if this entry represents a properly deleted (“scratched”) file. That is, if its file type is DEL and the closed flag is not set.
