Struct IdMap 

pub struct IdMap<V> {
    pub entries: Vec<(TxnId, V)>,
}

A map from transaction id, stored as a vector sorted by id; vstd specifies BTreeMap only for keys with an ordering spec, which TxnId lacks. Serialized as the JSON object the BTreeMap was.

Fields

entries: Vec<(TxnId, V)>

Sorted by id, ids unique. Read freely; change through the methods.

Trait Implementations

impl<V: Clone> Clone for IdMap<V>

fn clone(&self) -> IdMap<V>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<V: Debug> Debug for IdMap<V>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<V> Default for IdMap<V>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, V: Deserialize<'de>> Deserialize<'de> for IdMap<V>

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl<V> Index<&TxnId> for IdMap<V>

type Output = V

The returned type after indexing.

fn index(&self, id: &TxnId) -> &V

Performs the indexing (container[index]) operation.

impl<V: PartialEq> PartialEq for IdMap<V>

fn eq(&self, other: &IdMap<V>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<V: Serialize> Serialize for IdMap<V>

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl<V: Eq> Eq for IdMap<V>

impl<V> StructuralPartialEq for IdMap<V>
