Struct ReceiversBuilder

Source

pub struct ReceiversBuilder { /* private fields */ }

Expand description

Builder for creating Receivers programmatically.

This builder allows you to construct receiver configurations for signals when building DBC files programmatically.

§Examples

use dbc_rs::{ReceiversBuilder, SignalBuilder, ByteOrder};

// Broadcast receiver
let broadcast = ReceiversBuilder::new().broadcast().build()?;

// Specific nodes
let specific = ReceiversBuilder::new()
    .add_node("TCM")
    .add_node("BCM")
    .build()?;

// No receivers
let none = ReceiversBuilder::new().none().build()?;

// Use with signal builder
let signal = SignalBuilder::new()
    .name("RPM")
    .start_bit(0)
    .length(16)
    .byte_order(ByteOrder::BigEndian)
    .unsigned(true)
    .factor(0.25)
    .offset(0.0)
    .min(0.0)
    .max(8000.0)
    .receivers(ReceiversBuilder::new().add_node("TCM").add_node("BCM"))
    .build()?;

§Feature Requirements

This builder requires the std feature to be enabled.

Implementations§

Source §

impl ReceiversBuilder

Source

pub fn new() -> Self

Creates a new ReceiversBuilder with default settings (no receivers).

§Examples

use dbc_rs::ReceiversBuilder;

let builder = ReceiversBuilder::new();
let receivers = builder.build()?;
assert_eq!(receivers.len(), 0);

Source

pub fn broadcast(self) -> Self

Sets the receiver to broadcast (* in DBC format).

This clears any previously set nodes and sets the receiver to broadcast mode.

§Examples

use dbc_rs::ReceiversBuilder;

let receivers = ReceiversBuilder::new()
    .add_node("TCM")  // This will be cleared
    .broadcast()
    .build()?;
assert_eq!(receivers, dbc_rs::Receivers::Broadcast);

Source

pub fn none(self) -> Self

Sets the receiver to none (no explicit receivers).

This clears any previously set nodes and sets the receiver to none mode.

§Examples

use dbc_rs::ReceiversBuilder;

let receivers = ReceiversBuilder::new()
    .add_node("TCM")  // This will be cleared
    .none()
    .build()?;
assert_eq!(receivers, dbc_rs::Receivers::None);

Source

pub fn add_node(self, node: impl AsRef<str>) -> Self

Adds a single receiver node.

This automatically clears broadcast and none modes, switching to specific nodes mode.

§Arguments

node - The node name (anything that implements AsRef<str>)

§Examples

use dbc_rs::ReceiversBuilder;

let receivers = ReceiversBuilder::new()
    .add_node("TCM")
    .add_node("BCM")
    .build()?;
assert_eq!(receivers.len(), 2);
assert!(receivers.contains("TCM"));

Source

pub fn add_nodes<I, S>(self, nodes: I) -> Self
where I: IntoIterator<Item = S>, S: AsRef<str>,

Adds multiple receiver nodes from an iterator.

This automatically clears broadcast and none modes, switching to specific nodes mode.

§Arguments

nodes - An iterator of node names (each item must implement AsRef<str>)

§Examples

use dbc_rs::ReceiversBuilder;

// From a slice
let receivers = ReceiversBuilder::new()
    .add_nodes(&["TCM", "BCM", "ECM"])
    .build()?;
assert_eq!(receivers.len(), 3);

// From a vector
let node_vec = vec!["Node1", "Node2"];
let receivers2 = ReceiversBuilder::new()
    .add_nodes(node_vec.iter())
    .build()?;
assert_eq!(receivers2.len(), 2);

Source

pub fn clear(self) -> Self

Clears all receiver nodes and resets to default state (none).

§Examples

use dbc_rs::ReceiversBuilder;

let receivers = ReceiversBuilder::new()
    .add_node("TCM")
    .add_node("BCM")
    .clear()
    .add_node("ECM")
    .build()?;
assert_eq!(receivers.len(), 1);
assert!(receivers.contains("ECM"));
assert!(!receivers.contains("TCM"));

Source §

impl ReceiversBuilder

Source

pub fn build(&self) -> Result<Receivers>

Builds the Receivers from the builder configuration.

§Returns

Returns Ok(Receivers) if successful, or Err(Error::Signal) if:

More than 64 receiver nodes are specified (exceeds maximum limit)

§Examples

use dbc_rs::ReceiversBuilder;

// Broadcast
let broadcast = ReceiversBuilder::new().broadcast().build()?;

// Specific nodes
let nodes = ReceiversBuilder::new()
    .add_node("TCM")
    .add_node("BCM")
    .build()?;

// None (default)
let none = ReceiversBuilder::new().build()?;

§Errors

use dbc_rs::ReceiversBuilder;

// Too many nodes (limit is 64)
let mut builder = ReceiversBuilder::new();
for i in 0..65 {
    builder = builder.add_node(format!("Node{i}"));
}
assert!(builder.build().is_err());
