Struct flexbuffers::MapReader

pub struct MapReader<'de> { /* fields omitted */ }

Allows indexing on a flexbuffer map.

MapReaders may be indexed with strings or usizes. index returns a result type, which may indicate failure due to a missing key or bad data, idx returns an Null Reader in cases of error.

Implementations

impl<'de> MapReader<'de>

pub fn len(&self) -> usize

Returns the number of key/value pairs are in the map.

pub fn is_empty(&self) -> bool

Returns true if the map has zero key/value pairs.

pub fn index_key(&self, key: &str) -> Option<usize>

Returns the index of a given key in the map.

pub fn index<I: MapReaderIndexer>(&self, i: I) -> Result<Reader<'de>, Error>

Index into a map with a key or usize.

pub fn idx<I: MapReaderIndexer>(&self, i: I) -> Reader<'de>

Index into a map with a key or usize. If any errors occur a Null reader is returned.

pub fn iter_values(&self) -> ReaderIterator<'de>

Iterate over the values of the map.

pub fn iter_keys(
    &self
) -> impl Iterator<Item = &'de str> + DoubleEndedIterator + ExactSizeIterator + FusedIterator

Iterate over the keys of the map.

pub fn keys_vector(&self) -> VectorReader<'de>

Trait Implementations

impl<'de> Clone for MapReader<'de>

fn clone(&self) -> MapReader<'de>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'de> Debug for MapReader<'de>

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

Formats the value using the given formatter.

impl<'de> Default for MapReader<'de>

fn default() -> MapReader<'de>

Returns the "default value" for a type.
