Struct SeqMap 

pub struct SeqMap<V> { /* private fields */ }

Insertion-order-preserving String-keyed map with a mutable get-or-insert-default accessor. Same shape as graph::OrderedMap, kept as a separate small type here because that one exposes no get_mut/entry-style API. Public for the same reason as SeqSet – appears in ImpactWalkResult::visited.

Implementations

impl<V> SeqMap<V>

pub fn new() -> Self

Creates an empty insertion-ordered map.

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

Returns whether key is present.

pub fn insert(&mut self, key: String, value: V)

Inserts or replaces the value for key while preserving key order.

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

Iterates over entries in insertion order.

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

Iterates over keys in insertion order.
