Struct Fdt 

pub struct Fdt<'a> { /* private fields */ }

Implementations

impl<'a> Fdt<'a>

pub fn from_bytes(data: &'a [u8]) -> Result<Fdt<'a>, FdtError>

Create a new Fdt from byte slice.

pub unsafe fn from_ptr(ptr: *mut u8) -> Result<Fdt<'a>, FdtError>

Create a new Fdt from a raw pointer and size in bytes.

Safety

The caller must ensure that the pointer is valid and points to a memory region of at least size bytes that contains a valid device tree blob.

pub fn as_slice(&self) -> &'a [u8]

pub fn header(&self) -> &Header

Get a reference to the FDT header.

pub fn total_size(&self) -> usize

pub fn boot_cpuid_phys(&self) -> u32

This field shall contain the physical ID of the system’s boot CPU. It shall be identical to the physical ID given in the reg property of that CPU node within the devicetree.

pub fn raw(&self) -> &'a [u8]

Get a reference to the underlying buffer.

pub fn version(&self) -> u32

Get the FDT version

pub fn memory_reservation_blocks( &self, ) -> impl Iterator<Item = MemoryRegion> + 'a

pub fn all_nodes(&self) -> NodeIter<'a, 16>

pub fn find_nodes( &self, path: &'a str, ) -> impl Iterator<Item = Result<Node<'a>, FdtError>> + 'a

if path start with ‘/’ then search by path, else search by aliases

pub fn find_aliase(&self, name: &str) -> Result<&'a str, FdtError>

pub fn find_compatible<'b, 'c: 'b>( &'b self, with: &'c [&'c str], ) -> impl Iterator<Item = Result<Node<'a>, FdtError>> + 'b

pub fn chosen(&self) -> Result<Chosen<'a>, FdtError>

pub fn get_node_by_phandle( &self, phandle: Phandle, ) -> Result<Node<'a>, FdtError>

pub fn get_node_by_name(&'a self, name: &str) -> Result<Node<'a>, FdtError>

pub fn memory( &'a self, ) -> impl Iterator<Item = Result<Memory<'a>, FdtError>> + 'a

pub fn reserved_memory_regions( &self, ) -> Result<ReservedMemoryRegionsIter<'a>, FdtError>

Get all reserved-memory child nodes (memory regions)

Trait Implementations

impl<'a> Clone for Fdt<'a>

fn clone(&self) -> Fdt<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
