Struct FlitOhcA 

pub struct FlitOhcA {
    pub pasid: u32,
    pub fdwbe: u8,
    pub ldwbe: u8,
}

Parsed OHC-A word — the byte layout is shared by OHC-A1, OHC-A2, and OHC-A3.

OHC-A word byte layout (4 bytes, on-wire order):

Byte 0: flags[7:4] | PASID[19:16]
Byte 1: PASID[15:8]
Byte 2: PASID[7:0]
Byte 3: ldwbe[7:4] | fdwbe[3:0]

Use FlitOhcA::from_bytes to parse from a byte slice that starts at the first byte of the OHC-A word (i.e. at offset base_header_dw * 4 in the TLP).

Fields

pasid: u32

20-bit PASID value extracted from bytes 0–2.

fdwbe: u8

First DW byte enables (bits [3:0] of byte 3).

ldwbe: u8

Last DW byte enables (bits [7:4] of byte 3).

Implementations

impl FlitOhcA

pub fn from_bytes(b: &[u8]) -> Result<Self, TlpError>

Parse one OHC-A word from the first 4 bytes of b.

Returns Err(TlpError::InvalidLength) if b.len() < 4.

Trait Implementations

impl Clone for FlitOhcA

fn clone(&self) -> FlitOhcA

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlitOhcA

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

Formats the value using the given formatter.

impl PartialEq for FlitOhcA

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