Struct Node 

pub struct Node {
    pub value: Value,
    pub meta: Meta,
}

A value plus its Meta.

Fields

value: Value

meta: Meta

Implementations

impl Node

pub fn new(value: Value) -> Self

A node with no metadata.

pub fn with_meta(value: Value, meta: Meta) -> Self

A node with metadata.

pub fn at_position(self, position: Option<Position>) -> Self

Builder: set the source position.

pub fn is_container(&self) -> bool

Whether this is a sequence or a map.

pub fn len(&self) -> usize

The number of children of a container (0 for scalars).

pub fn is_empty(&self) -> bool

Whether this is an empty container or a scalar.

pub fn get(&self, key: &str) -> Option<&Node>

The value of key, for a map.

pub fn index(&self, index: usize) -> Option<&Node>

Item index, for a sequence.

pub fn at(&self, path: &Path) -> Option<&Node>

The node at path.

pub fn as_str(&self) -> Option<&str>

The string, for a string or date-time.

pub fn type_name(&self) -> &'static str

A short type name: null, bool, int, float, str, datetime, seq or map.

pub fn to_json(&self) -> Value

The value as JSON. Non-finite floats become null and date-times strings; metadata is dropped.

pub fn walk<'a>(&'a self, visit: impl FnMut(&Path, &'a Node))

Visit every node, parents before children, with its path.

pub fn redacted(&self, redactor: &dyn Redactor) -> Node

A copy with every string or number leaf that redactor masks replaced, keeping the structure.
