Struct TlpPacketHeader 

pub struct TlpPacketHeader { /* private fields */ }

TLP Packet Header Contains bytes for Packet header and informations about TLP type

Implementations

impl TlpPacketHeader

pub fn new(bytes: Vec<u8>, mode: TlpMode) -> Result<TlpPacketHeader, TlpError>

Create a new TlpPacketHeader from raw bytes and the specified framing mode.

Use TlpMode::NonFlit for PCIe 1.0–5.0 standard TLP framing. TlpMode::Flit is reserved for future PCIe 6.0 support and currently returns Err(TlpError::NotImplemented).

Errors

• TlpError::InvalidLength if bytes.len() < 4.
• TlpError::NotImplemented if mode is TlpMode::Flit.

pub fn tlp_type(&self) -> Result<TlpType, TlpError>

Decode and return the TLP type from the DW0 header fields.

Errors

• TlpError::InvalidFormat if the 3-bit Fmt field is not a known value.
• TlpError::InvalidType if the 5-bit Type field is not a known value.
• TlpError::UnsupportedCombination if Fmt and Type are individually valid but not a legal pair (e.g. IO Request with 4DW header).

pub fn get_tlp_type(&self) -> Result<TlpType, TlpError>

👎Deprecated since 0.5.0:

use tlp_type() instead

Decode and return the TLP type from the DW0 header fields.

Deprecation

Prefer TlpPacketHeader::tlp_type which follows Rust naming conventions.

pub fn get_tc(&self) -> u32

Raw Traffic Class field from DW0 (bits[11:9]).

Trait Implementations

impl Debug for TlpPacketHeader

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

Formats the value using the given formatter.
