Struct DialectLayers 

pub struct DialectLayers { /* private fields */ }

A report’s primary format layer and any nested or carried format layers.

Extra layers are unique by (format, instance). An extra layer for the primary format has an instance that identifies it inside the containing document. The wire names the primary explicitly, so the collection carries its complete identity without an enclosing report’s format.

A read rejects a wire whose extra repeats a (format, instance) key, and one whose extra carries the primary key. The key set on the wire is the key set of the value, so no layer is silently discarded or overwritten.

Implementations

impl DialectLayers

pub fn of(primary: DialectMatch) -> Self

Constructs dialect layers with one primary and no extra layers.

pub fn insert(&mut self, layer: DialectMatch) -> Result<(), DialectLayerError>

Inserts a layer keyed by (format, instance).

The first layer for a key remains authoritative. A duplicate is returned unchanged so its producer can report the collision.

pub fn with(self, layer: DialectMatch) -> Result<Self, DialectLayerError>

Adds a layer, returning it unchanged when its key is occupied.

pub fn primary(&self) -> &DialectMatch

Returns the report’s primary format layer.

pub fn iter(&self) -> impl Iterator<Item = &DialectMatch>

Iterates over the primary layer followed by every extra layer.
