Struct DiskDirEntry 

Source
#[repr(C)]
pub struct DiskDirEntry { pub inode: u32, pub rec_len: u16, pub name_len: u8, pub file_type: u8, pub name: [u8; 255], }
Expand description

On-disk directory entry (ext2-style variable-length record)

Layout:

  • inode: 4 bytes (inode number, 0 = deleted entry)
  • rec_len: 2 bytes (total record length, always 4-byte aligned)
  • name_len: 1 byte (actual name length)
  • file_type: 1 byte (1=file, 2=directory)
  • name: up to 255 bytes
