Struct pot::ser::SymbolMap

pub struct SymbolMap { /* private fields */ }

A list of previously serialized symbols.

Implementations

impl SymbolMap

pub const fn new() -> Self

Returns a new, empty symbol map.

pub fn serializer_for<W: WriteBytesExt>( &mut self, output: W ) -> Result<Serializer<'_, W>>

Returns a serializer that writes into output and persists symbols into self.

pub fn serialize_to<T, W>(&mut self, writer: W, value: &T) -> Result<()>where W: Write, T: Serialize,

Serializes value into writer while persisting symbols into self.

pub fn serialize_to_vec<T>(&mut self, value: &T) -> Result<Vec<u8>>where T: Serialize,

Serializes value into a new Vec<u8> while persisting symbols into self.

pub fn insert(&mut self, symbol: &str) -> bool

Inserts symbol into this map.

Returns true if this symbol had not previously been registered. Returns false if the symbol was already included in the map.

pub fn len(&self) -> usize

Returns the number of entries in this map.

pub fn is_empty(&self) -> bool

Returns true if the map has no entries.

pub fn populate_from<T>( &mut self, value: &T ) -> Result<usize, SymbolMapPopulationError>where T: Serialize,

Adds all symbols encountered in value.

Returns the number of symbols added.

Due to how serde works, this function can only encounter symbols that are being used. For example, if T is an enum, only variant being passed in will have its name, and additional calls for each variant will be needed to ensure every symbol is added.

Trait Implementations

impl Debug for SymbolMap

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

Formats the value using the given formatter.

impl Default for SymbolMap

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SymbolMap

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for SymbolMap

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where S: Serializer,

Serialize this value into the given Serde serializer.
