Struct ketos::name::NameMapSlice

pub struct NameMapSlice<T> { /* fields omitted */ }

Maps names to values in a sorted boxed slice.

Values may overwrite existing values, but new names cannot be inserted.

Methods

impl<T> NameMapSlice<T>

fn contains_key(&self, name: Name) -> bool

Returns whether the map contains a value for the given name.

fn index(&self, name: Name) -> Option<usize>

Returns the index within the internal Vec of the given key.

fn get(&self, name: Name) -> Option<&T>

Returns the value corresponding to the given name.

fn values(&self) -> &[(Name, T)]

Returns a slice of the contained names and values.

fn set(&mut self, name: Name, value: T) -> Option<T>

Overwrites the value for the given name.

Returns None if the name does not exist in the mapping. When None is returned, no value will have been stored in the mapping.

fn is_empty(&self) -> bool

Returns whether the given map is empty.

fn iter(&self) -> Iter<(Name, T)>

Returns an iterator over names and values.

fn into_name_map(self) -> NameMap<T>

Elevates the map into NameMap, which may receive new key-value pairs.

fn len(&self) -> usize

Returns the number of name-value pairs contained in the map.

Trait Implementations

impl<T: Clone> Clone for NameMapSlice<T>

fn clone(&self) -> NameMapSlice<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for NameMapSlice<T>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<T: Default> Default for NameMapSlice<T>

fn default() -> NameMapSlice<T>

Returns the "default value" for a type.

impl<T: Eq> Eq for NameMapSlice<T>

impl<T: PartialEq> PartialEq for NameMapSlice<T>

fn eq(&self, __arg_0: &NameMapSlice<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &NameMapSlice<T>) -> bool

This method tests for !=.

impl<T> FromIterator<(Name, T)> for NameMapSlice<T>

fn from_iter<I>(iterator: I) -> Self where I: IntoIterator<Item=(Name, T)>

Creates a value from an iterator.

impl<'a, T> IntoIterator for &'a NameMapSlice<T>

type Item = &'a (Name, T)

The type of the elements being iterated over.

type IntoIter = Iter<'a, (Name, T)>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Iter<'a, (Name, T)>

Creates an iterator from a value.
