Struct CodeDictionary 

pub struct CodeDictionary<T: Eq + Hash> { /* private fields */ }

Available on crate feature std only.

Simple auto-incrementing dictionary indexed by hash value. Creates new codes for new values when first seen. Increments in order of query.

Implementations

impl<T: Eq + Hash + Default> CodeDictionary<T>

pub fn new() -> CodeDictionary<T>

impl<T: Eq + Hash + Clone> CodeDictionary<T>

pub fn lookup_value(&self, value: &T) -> Option<u32>

Looks up a code for a specific value

pub fn get_code(&mut self, value: &T) -> (bool, u32)

Returns the code for the specified value and if a new code was generated for the value (first time seeing the value).

pub fn read_code<F: FnOnce() -> Result<T, E>, E>( &mut self, code: u32, value_producer: F, ) -> Result<T, E>
