Struct CapacityExtensions 

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

Metadata this build does not interpret, preserved verbatim.

The same guarantee the sibling registries give their records (crate::cycle_schedule::config::CycleScheduleExtensions, crate::roadmap::registry::InitiativeExtensions): a key a newer tix adds must survive an edit-and-save round trip instead of being dropped. The one rule it cannot break is that a preserved key must not shadow a built-in field — a file can never deliver such a key (serde matches the known field first), but the public write path could inject one, and toml serializes duplicate table keys without complaining, so the write would appear to succeed while the next load failed on a duplicate key. validate refuses it instead.

Implementations

impl CapacityExtensions

pub fn is_empty(&self) -> bool

Whether no unknown metadata is present.

pub fn len(&self) -> usize

The number of preserved keys.

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

Look up a preserved key.

pub fn keys(&self) -> impl Iterator<Item = &str>

The preserved keys, in canonical order.

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

Iterate the preserved (key, value) pairs in canonical order.

pub fn table(&self) -> &Table

The underlying table, for a caller that must serialize it whole.

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

Preserve one (key, value) pair, returning the previous value if any.
