Struct TimestampCapabilities 

pub struct TimestampCapabilities {
    pub software_tx: bool,
    pub software_rx: bool,
    pub hardware_tx: bool,
    pub hardware_rx: bool,
}

Timestamping capabilities of a network interface.

Fields

software_tx: bool

software_rx: bool

hardware_tx: bool

hardware_rx: bool

Implementations

impl TimestampCapabilities

pub fn query(interface_name: &str) -> Result<Self>

Query the timestamping capabilities of a network interface (Linux).

Uses a best-effort approach:

1. Checks if the interface exists via /sys/class/net/{iface}.
2. Checks if it has a backing hardware device via /sys/class/net/{iface}/device/. Hardware devices with PCI backing often support hardware timestamping.
3. Attempts SIOCETHTOOL with ETHTOOL_GET_TS_INFO ioctl for precise capability detection.
4. Falls back to software_only() if detection fails.

Software timestamping is always assumed available on Linux (kernel provides it).

pub fn software_only() -> Self

Return default software-only capabilities (fallback).

pub fn hardware() -> Self

Return capabilities indicating full hardware timestamping support.

pub fn has_hardware(&self) -> bool

Whether any form of hardware timestamping is available.

pub fn has_software(&self) -> bool

Whether software timestamping is available (always true on Linux/FreeBSD).
