Struct Chosen 

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

The /chosen node containing boot parameters.

This node contains system configuration parameters chosen by the firmware or bootloader, such as boot arguments, console paths, and other boot-time settings.

Implementations

impl<'a> Chosen<'a>

pub fn bootargs(&self) -> Option<&'a str>

Returns the bootargs property value.

This property contains command-line arguments to be passed to the operating system kernel.

pub fn stdout_path(&self) -> Option<&'a str>

Returns the stdout-path property value.

This property specifies the path to the device to be used for standard output (console).

pub fn stdin_path(&self) -> Option<&'a str>

Returns the stdin-path property value.

This property specifies the path to the device to be used for standard input.

Methods from Deref<Target = NodeBase<'a>>

pub fn name(&self) -> &'a str

Returns the node’s name.

pub fn level(&self) -> usize

Returns the depth/level of this node in the tree.

pub fn properties(&self) -> PropIter<'a>

Returns an iterator over this node’s properties.

pub fn find_property(&self, name: &str) -> Option<Property<'a>>

Finds a property by name.

pub fn find_property_str(&self, name: &str) -> Option<&'a str>

Finds a string property by name.

pub fn reg(&self) -> Option<RegIter<'a>>

Finds and parses the reg property, returning a Reg iterator.

pub fn reg_array<const N: usize>(&self) -> Vec<RegInfo, N>

Finds and parses the reg property, returning all RegInfo entries.

pub fn ranges(&self) -> Option<VecRange<'a>>

Returns the ranges property if present.

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

Returns an iterator over compatible strings.

pub fn path(&self) -> String<256>

Returns the full path of this node as a string.

For the root node, returns “/”. For other nodes, returns the absolute path like “/soc/serial@0”.
