Struct thrift_codec::data::Map

pub struct Map(/* private fields */);

Map.

Internally this is represented by the data structure called “associative array”. No duplicate keys are removed.

Implementations

impl Map

pub fn empty() -> Self

Makes an empty Map instance.

Note that the returning value could not be encoded by the binary protocol encoding.

pub fn new<I, K, V>(pairs: I) -> Self

where I: Iterator<Item = (K, V)>, Vec<K>: Into<Elements>, Vec<V>: Into<Elements>,

Makes a new Map instance.

pub fn from_keys_and_values(keys: Elements, values: Elements) -> Result<Self>

Makes a new Map instance from the separate keys and values.

Errors

If the lengths of keys and values are differed, this function will return an error which kind is ErrorKind::InvalidInput.

pub fn get(&self, index: usize) -> Option<(DataRef<'_>, DataRef<'_>)>

Returns the entry placed at the specified index.

pub fn iter(&self) -> MapIter<'_>

Returns an iterator over this map.

pub fn key_kind(&self) -> Option<DataKind>

Returns the kind of the keys in this map.

pub fn value_kind(&self) -> Option<DataKind>

Returns the kind of the values in this map.

pub fn len(&self) -> usize

Returns the number of the entries in this map.

pub fn is_empty(&self) -> bool

Returns true if this map has no entries.

Trait Implementations

impl BinaryDecode for Map

fn binary_decode<R: Read>(reader: &mut R) -> Result<Self>

Decodes an object.

impl BinaryEncode for Map

fn binary_encode<W: Write>(&self, writer: &mut W) -> Result<()>

Encodes an object.

impl Clone for Map

fn clone(&self) -> Map

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CompactDecode for Map

fn compact_decode<R: Read>(reader: &mut R) -> Result<Self>

Decodes an object.

impl CompactEncode for Map

fn compact_encode<W: Write>(&self, writer: &mut W) -> Result<()>

Encodes an object.

impl Debug for Map

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

Formats the value using the given formatter.

impl From<Map> for Data

fn from(f: Map) -> Self

Converts to this type from the input type.

impl PartialEq for Map

fn eq(&self, other: &Map) -> 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.
