Struct Tree 

pub struct Tree<'a, E: Elem + Into<u32>, C: Component> {
    pub buf: &'a [E],
    pub component: &'a C,
}

Represents a section of a component tree that’s present in a buffer.

Fields

buf: &'a [E]

component: &'a C

Implementations

impl<'a, E: Elem + Into<u32>, C: Component> Tree<'a, E, C>

pub fn new(buf: &'a [E], component: &'a C) -> Self

Returns the component tree rooted at the given component.

pub fn map<SUBC: Component>( &self, f: impl FnOnce(&'a C) -> &'a SUBC, ) -> Tree<'a, E, SUBC>

Descends into a subtree. The given function should return the requested layout based when passed this tree’s layout.

pub fn get_u32s(&self) -> Result<Vec<u32>>

Interprets the contents of this tree as a list of u32s.

pub fn get_bytes(&self) -> Result<Vec<u8>>

Interprets the contents of this tree as a list of bytes.

pub fn get_shorts(&self) -> Result<Vec<u16>>

Interprets the contents of this tree as a list of shorts.

pub fn get_digest_from_shorts(&self) -> Result<Digest>

Interprets the contents of this tree as a digest based on a list of shorts.

pub fn get_u32_from_bytes(&self) -> Result<u32>

Returns the contents of this tree as a u32; elements are expected to be 4 bytes.

pub fn get_u32_from_elem(&self) -> Result<u32>

Returns the contents of this tree, which should have a single element, as a u32.

Trait Implementations

impl<'a, E: Clone + Elem + Into<u32>, C: Clone + Component> Clone for Tree<'a, E, C>

fn clone(&self) -> Tree<'a, E, C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Elem + Into<u32>, C: Component> Debug for Tree<'_, E, C>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
