Struct PeekMap 

pub struct PeekMap<'mem, 'facet> { /* private fields */ }

Lets you read from a map (implements read-only facet_core::MapVTable proxies)

Implementations

impl<'mem, 'facet> PeekMap<'mem, 'facet>

pub fn new(value: Peek<'mem, 'facet>, def: MapDef) -> Self

Constructor

pub fn len(&self) -> usize

Get the number of entries in the map

pub fn is_empty(&self) -> bool

Returns true if the map is empty

pub fn contains_key(&self, key: &impl Facet<'facet>) -> bool

Check if the map contains a key

pub fn get<'k>(&self, key: &'k impl Facet<'facet>) -> Option<Peek<'mem, 'facet>>

Get a value from the map for the given key

pub fn iter(self) -> PeekMapIter<'mem, 'facet>

Returns an iterator over the key-value pairs in the map

pub fn def(&self) -> MapDef

Def getter
