Struct AgentMeta 

pub struct AgentMeta {
    pub entries: Vec<MetaEntry>,
}

Fields

entries: Vec<MetaEntry>

Operator-entered key/value rows, in display order. Producers should go through AgentMeta::new / AgentMeta::upsert / AgentMeta::remove so the invariants below hold; consumers can then rely on them: unique non-empty keys, each trimmed.

Implementations

impl AgentMeta

pub fn new<I: IntoIterator<Item = MetaEntry>>(entries: I) -> Self

Construct from any iterator of entries, normalising: trim key and value, drop rows whose key is empty, and de-dup by key keeping the last occurrence’s value while preserving each key’s first-seen position. So two operators who enter the same logical set (any trailing whitespace / duplicate key / re-ordered) converge on the same stored JSON for a given field order.

pub fn upsert( &mut self, key: impl Into<String>, value: impl Into<String>, ) -> bool

Set a key to a value (insert or overwrite). Trims both. Returns true if the stored set changed (new key, or a different value for an existing key), false on a no-op. An empty (post-trim) key is rejected as a no-op — use AgentMeta::remove to drop a key.

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

Remove a key. Returns true if it was present.

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

pub fn is_empty(&self) -> bool
