Struct LfoFileHeader 

pub struct LfoFileHeader {
    pub magic: u32,
    pub unk_cst1: u16,
    pub comp_format: u16,
    pub payload_size: u32,
    pub data_hash: [u8; 32],
    pub cur_payload_size: u32,
    pub cur_state: u16,
    pub unk: u16,
}

Reproduces the internal format of the LFO file headers, as used by the official client If you just care about downloading a file, you probably don’t need to look at this struct.

Fields

magic: u32

Constant value (“RHDL”)

unk_cst1: u16

Unclear, I have only seen the constant value 1 passed around

comp_format: u16

See CompressionFormats for known values

payload_size: u32

The size of the requested file data, after any decompression

data_hash: [u8; 32]

Sha256 hash of the final data, without LFO header and after any decompression

cur_payload_size: u32

In the official client, this field gets updated as it receives more data. You should ignore this field.

cur_state: u16

In the official client, this starts at 1, goes up to 5 as we continue downloading. Ignore this field.

unk: u16

This field is physically present in LFO headers, but its purpose has not been documented.

Trait Implementations

impl Clone for LfoFileHeader

fn clone(&self) -> LfoFileHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LfoFileHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LfoFileHeader

fn eq(&self, other: &LfoFileHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&[u8]> for LfoFileHeader

type Error = String

The type returned in the event of a conversion error.

fn try_from(lfo_payload: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.
