Crate taktora_ethercat_netcfg 

Parser and in-memory IR for the EtherCAT network-config YAML.

This crate is the parse layer of the taktora-ethercat-netcfg codegen toolchain (a build-host tool — std is fine). It turns a network.yaml document into the NetworkConfig IR via the single public entry point parse.

It performs parsing only. Validation, address assignment, multi-bus handling, and code generation are deliberately out of scope here — they are handled by later layers of the toolchain.

Structs

BusConfig

Bus-wide configuration.

ChannelBinding

A binding from a named channel to a slice of a device’s process data.

DeviceInstance

A single device instance declared on the bus.

Identity

The vendor / product / revision triple identifying a fieldbus device.

NetworkConfig

The fully parsed network configuration — the IR root.

PdoEntry

A single PDO entry within an inline device description.

SmWatchdogRegisters

Resolved ESC SM-watchdog register values for one output device.

StartupSdoSpec

One operator-declared startup SDO, written in PRE-OP before PDO assignment.

Enums

DeviceSource

The origin of a device’s PDO description.

ElementType

Primitive inline element types for a channel.

NetcfgError

Errors that can occur while parse-ing a network config.

PdoDirection

Direction of a process-data channel.

SdoValueSpec

A typed startup-SDO value. Mirrors taktora_connector_ethercat::SdoValue; codegen emits the matching connector variant as text.

Constants

DEFAULT_WATCHDOG_DIVIDER

Watchdog divider that yields a 100 µs tick: 40 ns × (2498 + 2) = 100 µs.

Functions

parse

Parse a network-config YAML document into the NetworkConfig IR.

sm_watchdog_intervals

Quantize a timeout in microseconds to a whole number of 100 µs watchdog ticks: intervals = ceil(timeout_us / 100), clamped to 1..=u16::MAX.
