Struct FlatNode

pub struct FlatNode {
    pub children: IndexMap<String, Option<String>>,
    pub inherits: IndexMap<String, String>,
    pub attributes: IndexMap<String, Arc<Value>>,
}

All opinions about one path, merged in layer order.

Upstream calls this a pre-composition node. References are still paths; composition resolves them.

Fields

children: IndexMap<String, Option<String>>

Child name to referenced path. A None value survives flattening so that composition can delete a child inherited from elsewhere.

inherits: IndexMap<String, String>

Inherit name to referenced path. null entries are already applied and removed.

attributes: IndexMap<String, Arc<Value>>

Attribute values. A JSON null is kept as a value, as upstream does; it does not delete the attribute.

Implementations

impl FlatNode

pub fn merge(&mut self, node: &IfcxNode)

Merges one later opinion into this node.

For each map, entries of node are applied in their order and replace an existing entry of the same name in place:

• children: the value is stored as written, None included;
• inherits: None removes the entry, a path sets it;
• attributes: the value is stored as written, null included.

The node’s path and unknown fields are not looked at.

pub fn merge_owned(&mut self, node: IfcxNode)

Merges one later opinion into this node, moving its maps and attribute values instead of copying them. Same rules as merge.

Trait Implementations

impl Clone for FlatNode

fn clone(&self) -> FlatNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FlatNode

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

Formats the value using the given formatter.

impl Default for FlatNode

fn default() -> FlatNode

Returns the “default value” for a type.

impl PartialEq for FlatNode

fn eq(&self, other: &FlatNode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
