Struct FutuHeader 

pub struct FutuHeader {
    pub proto_id: u32,
    pub proto_fmt_type: ProtoFmtType,
    pub proto_ver: u8,
    pub serial_no: u32,
    pub body_len: u32,
    pub body_sha1: [u8; 20],
}

Stable API — FutuOpenD API 协议帧头（44 字节，手工 encode/decode）。

Fields

proto_id: u32

proto_fmt_type: ProtoFmtType

proto_ver: u8

serial_no: u32

body_len: u32

body_sha1: [u8; 20]

Implementations

impl FutuHeader

pub fn peek(src: &BytesMut) -> Result<Option<Self>, FutuError>

Stable API — 从 BytesMut 中解析帧头（不消费 bytes，仅 peek）。

返回 None 如果数据不足 HEADER_SIZE 字节。 返回 Err 如果 magic bytes 不匹配或格式类型无效。

pub fn decode(src: &mut BytesMut) -> Result<Option<Self>, FutuError>

Stable API — 从 BytesMut 中解析并消费帧头（成功时 advance HEADER_SIZE bytes）。

pub fn encode(&self, dst: &mut BytesMut)

Stable API — 将帧头写入 BytesMut（44 字节，LE 序 + MAGIC + SHA1 + reserved）。

Trait Implementations

impl Clone for FutuHeader

fn clone(&self) -> FutuHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FutuHeader

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

Formats the value using the given formatter.

impl PartialEq for FutuHeader

fn eq(&self, other: &FutuHeader) -> 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.
