Struct Node 

pub struct Node {
    pub name: String,
    /* private fields */
}

A mutable device tree node.

Represents a node in the device tree with a name, properties, and child node IDs. Nodes are stored in a flat BTreeMap<NodeId, Node> within the Fdt struct, and children are referenced by their NodeId.

Fields

name: String

Node name (without path)

Implementations

impl Node

pub fn new(name: &str) -> Self

Creates a new node with the given name.

pub fn name(&self) -> &str

Returns the node’s name.

pub fn properties(&self) -> &[Property]

Returns an iterator over the node’s properties.

pub fn children(&self) -> &[NodeId]

Returns the child node IDs.

pub fn add_child(&mut self, name: &str, id: NodeId)

Adds a child node ID to this node.

Updates the name cache for fast lookups.

pub fn add_property(&mut self, prop: Property)

Adds a property to this node.

Updates the property cache for fast lookups.

pub fn get_child(&self, name: &str) -> Option<NodeId>

Gets a child node ID by name.

Uses the cache for fast lookup.

pub fn remove_child(&mut self, name: &str) -> Option<NodeId>

Removes a child node by name, returning its NodeId.

Rebuilds the name cache after removal.

pub fn set_property(&mut self, prop: Property)

Sets a property, adding it if it doesn’t exist or updating if it does.

pub fn get_property(&self, name: &str) -> Option<&Property>

Gets a property by name.

pub fn get_property_mut(&mut self, name: &str) -> Option<&mut Property>

Gets a mutable reference to a property by name.

pub fn remove_property(&mut self, name: &str) -> Option<Property>

Removes a property by name.

Updates indices after removal to keep the cache consistent.

pub fn address_cells(&self) -> Option<u32>

Returns the #address-cells property value.

pub fn size_cells(&self) -> Option<u32>

Returns the #size-cells property value.

pub fn phandle(&self) -> Option<Phandle>

Returns the phandle property value.

pub fn interrupt_parent(&self) -> Option<Phandle>

Returns the local interrupt-parent property value.

pub fn status(&self) -> Option<Status>

Returns the status property value.

pub fn ranges(&self, parent_address_cells: u32) -> Option<Vec<RangesEntry>>

Parses the ranges property for address translation.

Returns a vector of range entries mapping child bus addresses to parent bus addresses.

pub fn compatible(&self) -> Option<impl Iterator<Item = &str>>

Returns the compatible property as a string iterator.

pub fn compatibles(&self) -> impl Iterator<Item = &str>

Returns an iterator over all compatible strings.

pub fn device_type(&self) -> Option<&str>

Returns the device_type property value.

pub fn is_memory(&self) -> bool

Returns true if this node is a memory node.

pub fn is_interrupt_controller(&self) -> bool

Returns true if this node is an interrupt controller.

pub fn interrupt_cells(&self) -> Option<u32>

Returns the #interrupt-cells property value.

pub fn is_clock(&self) -> bool

Returns true if this node is a clock provider.

pub fn is_pci(&self) -> bool

Returns true if this node is a PCI bridge.
