Struct cros_fdt::FdtNode

pub struct FdtNode {
    pub(crate) name: String,
    pub(crate) props: IndexMap<String, Vec<u8>>,
    pub(crate) subnodes: IndexMap<String, FdtNode>,
}

Flattened device tree node.

This represents a single node from the FDT structure block. Every node may contain properties and other (child) nodes.

Fields

name: String

Node name

props: IndexMap<String, Vec<u8>>

subnodes: IndexMap<String, FdtNode>

Implementations

impl FdtNode

pub(crate) fn new( name: String, props: IndexMap<String, Vec<u8>>, subnodes: IndexMap<String, FdtNode> ) -> Result<Self>

pub(crate) fn empty(name: impl Into<String>) -> Result<Self>

fn read_token(input: &mut &'_ [u8]) -> Result<u32>

fn parse_node(input: &mut &'_ [u8], strings: &FdtStrings) -> Result<Self>

fn from_blob(input: &'_ [u8], strings: &FdtStrings) -> Result<Self>

fn write_blob( &self, writer: &mut impl Write, strings: &mut FdtStrings ) -> Result<()>

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

pub(crate) fn has_prop(&self, name: &str) -> bool

pub fn get_prop<T>(&self, name: &str) -> Option<T>

where T: FromFdtPropval,

Read property value if it exists.

Arguments

name - name of the property.

pub(crate) fn phandle_at_offset(&self, name: &str, offset: usize) -> Option<u32>

pub(crate) fn update_phandle_at_offset( &mut self, name: &str, offset: usize, phandle: u32 ) -> Result<()>

pub fn set_prop<T>(&mut self, name: &str, value: T) -> Result<()>

where T: ToFdtPropval,

Write a property.

Arguments

name - name of the property; must be a valid property name according to DT spec. val - value of the property (raw byte array).

pub fn subnode(&self, name: &str) -> Option<&FdtNode>

Return a reference to an existing subnode with given name, or None if it doesn’t exist.

Arguments

name - name of the node.

pub fn subnode_mut(&mut self, name: &str) -> Result<&mut FdtNode>

Create a node if it doesn’t already exist, and return a mutable reference to it. Return an error if the node name is not valid.

Arguments

name - name of the node; must be a valid node name according to DT specification.

pub(crate) fn iter_subnodes(&self) -> impl Iterator<Item = &FdtNode>

pub(crate) fn iter_subnodes_mut(&mut self) -> impl Iterator<Item = &mut FdtNode>
