Struct Tree 

pub struct Tree { /* private fields */ }

A parsed ASDF tree.

Implementations

impl Tree

pub fn root(&self) -> Option<Value<'_>>

The root value.

pub fn get(&self, path: &str) -> Option<Value<'_>>

The value at a path, using ASDF’s YAML Pointer syntax.

A numeric component indexes a sequence or names a mapping key depending on what its parent is; negative indices count from the end.

pub fn read_array(&self, array: &Ndarray) -> Result<Vec<Element>>

Read every element of an array whose data is inline in this tree.

Inline data needs no file: the values are already here. An array backed by a block is read through AsdfFile::read_array instead, and is an error here.

pub fn meta(&self) -> Result<Meta>

What this file says about itself: what wrote it, and its history.

Everything in it is optional, so a file that says nothing yields an empty Meta rather than an error.

pub fn document(&self) -> &Document

The underlying document, for callers needing the lower-level model.

pub fn value_eq(&self, other: &Tree) -> bool

Whether two trees represent the same values.

Presentation – flow versus block, quoting, integer width – is ignored; tags, values, sequence order and the set of keys are not.

pub fn to_yaml(&self) -> Result<String>

Render the tree back to YAML.

Trait Implementations

impl Clone for Tree

fn clone(&self) -> Self

Returns a duplicate of the value.

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

impl Debug for Tree

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