# RedoxFS Design Document

|
## Structures
|
|
|
|
### Header
|
|
The header is the entry point for the filesystem. When mounting a disk or image, it should be scanned for a block starting with the 8-byte signature, within the first megabyte:
|
|
```rust
|
|
"RedoxFS\0"
|
|
```
|
|
|
|
The header stores the filesystem version, disk identifier, disk size, root block pointer, and free block pointer.
|
|
|
|
```rust
|
|
#[repr(packed)]
|
|
pub struct Header {
|
|
pub signature: [u8; 8],
|
|
pub version: u64,
|
|
pub uuid: [u8; 16],
|
|
pub size: u64,
|
|
pub root: u64,
|
|
pub free: u64,
|
|
}
|
|
```
|
|
|
|
The root and free block pointers point to a Node that identifies
|
|
|
|
### Node
|
|
|
|
```rust
|
|
#[repr(packed)]
|
|
pub struct Node {
|
|
pub name: [u8; 256],
|
|
pub mode: u64,
|
|
pub next: u64,
|
|
pub extents: [Extent; 15],
|
|
}
|
|
```
