Enum QueryResult 

pub enum QueryResult<V> {
    Val(V),
    Partial,
    Missing,
}

The result of querying a [Try] for a particular Key.

Variants

Val(V)

A leaf value associated with the key used in the query

Partial

The key used to query is a prefix to multiple targets

Missing

The key does not exist within the Trie

Implementations

impl<V> QueryResult<V>

pub fn map<F, U>(self, f: F) -> QueryResult<U>

where F: Fn(V) -> U,

Trait Implementations

impl<V: Clone> Clone for QueryResult<V>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<V: Debug> Debug for QueryResult<V>

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

Formats the value using the given formatter.

impl<V> From<Option<V>> for QueryResult<V>

fn from(opt: Option<V>) -> Self

Converts to this type from the input type.

impl<V> From<QueryResult<V>> for Option<V>

fn from(q: QueryResult<V>) -> Self

Converts to this type from the input type.

impl<V: PartialEq> PartialEq for QueryResult<V>

fn eq(&self, other: &QueryResult<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.
