Struct ExtensionsV1 

pub struct ExtensionsV1(/* private fields */);

Ordered, bounded storage for additive top-level V1 fields.

The map is intentionally a newtype instead of an alias so both deserialization and programmatic insertion enforce the same bounds. Each owning DTO applies its own reserved-field validation when it validates the decoded value.

Implementations

impl ExtensionsV1

pub fn insert( &mut self, key: impl Into<String>, value: Value, ) -> Result<Option<Value>, ValidationError>

Add one extension after validating its key and JSON value.

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

Return one retained additive value.

pub fn contains_key(&self, key: &str) -> bool

Check whether one additive field is retained.

pub fn iter(&self) -> impl Iterator<Item = (&String, &Value)>

Iterate over retained additive fields in lexical order.

pub fn as_map(&self) -> &BTreeMap<String, Value>

Borrow the validated map.

pub fn into_inner(self) -> BTreeMap<String, Value>

Consume the wrapper and return the validated map.
