Struct mica::ll::value::Dict

pub struct Dict { /* private fields */ }

A dict (dictionary) storing arbitrarily typed keys and values.

Note that this type has interior mutability. This is because dicts in Mica are shared by reference; creating a new dict requires using clone.

Implementations

impl Dict

pub fn new() -> Self

Creates a new dict.

pub fn len(&self) -> usize

Returns the number of elements stored in the dict.

pub fn is_empty(&self) -> bool

Returns whether the dict is empty.

pub fn insert(&self, key: RawValue, value: RawValue) -> RawValue

Sets the value at the given key. Returns the old value, or nil if there was no value.

pub fn remove(&self, key: RawValue) -> RawValue

Removes the value at the given key and returns it (or nil if there was no value).

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

Returns the value under the given key, or None if there is no such value.

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

Returns whether the dict contains a value under the given key.

Trait Implementations

impl Clone for Dict

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Dict

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

Formats the value using the given formatter.

impl Default for Dict

fn default() -> Dict

Returns the “default value” for a type.

impl PartialEq<Dict> for Dict

fn eq(&self, other: &Self) -> bool

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

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

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

impl SelfFromRawValue for Dict

type Guard = ()

A scoped guard, ensuring safe access to Self.

unsafe fn self_from_raw_value(
    v: &RawValue
) -> Result<(&Self, Self::Guard), Error>

Returns a shared reference to Self without checking that the value is of the correct type.
