Struct symtern::adaptors::Inline

pub struct Inline<W> { /* fields omitted */ }

Interner optimized for short strings.

See the module-level documentation for more information.

Methods

impl<W> Inline<W>

fn new() -> Self where W: Default

Create a new, empty symbol pool

Trait Implementations

impl<W: Copy> Copy for Inline<W>

impl<W: Clone> Clone for Inline<W>

fn clone(&self) -> Inline<W>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<W: Debug> Debug for Inline<W>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<W> Default for Inline<W> where W: Default

fn default() -> Self

Returns the "default value" for a type.

impl<W> From<W> for Inline<W>

fn from(w: W) -> Self

Performs the conversion.

impl<W> Len for Inline<W> where W: Len + Pool, W::Symbol::Id: Pack + ToPrimitive

fn len(&self) -> usize

Fetch the number of items contained in the pool. The returned value does not count values inlined in symbols.

fn is_empty(&self) -> bool

Check if the pool is "empty", i.e. has zero stored values.

Because strings inlined in symbols are not stored in the pool, they do not affect the result of this method.

fn is_full(&self) -> bool

Check if the number of interned symbols has reached the maximum allowed for the pool's ID type.

impl<'a, W, WS> Intern for &'a Inline<W> where W: Len + Pool<Symbol=WS>, &'a W: Intern<Input=str, Symbol=W::Symbol>, WS: Symbol, WS::Id: Pack

type Input = str

Type of value accepted by intern.

type Symbol = Sym<WS>

Type used to represent interned values.

fn intern(self, s: &Self::Input) -> Result<Self::Symbol>

Fetch the symbol that corresponds to the given value. If the value does not map to any existing symbol, create and return a new one. This method may return an error if the interner encounters any error while storing the value.

impl<'a, W, WS> Intern for &'a mut Inline<W> where W: Len + Pool<Symbol=WS>, &'a mut W: Intern<Input=str, Symbol=W::Symbol>, WS: Symbol, WS::Id: Pack

type Input = str

Type of value accepted by intern.

type Symbol = Sym<WS>

Type used to represent interned values.

fn intern(self, s: &Self::Input) -> Result<Self::Symbol>

Fetch the symbol that corresponds to the given value. If the value does not map to any existing symbol, create and return a new one. This method may return an error if the interner encounters any error while storing the value.

impl<'a, W, WS> Resolve for &'a Inline<W> where &'b W: Resolve<Input=WS, Output=&'b str>, WS: 'a + Symbol, WS::Id: Pack + SymbolId

type Input = &'a Sym<WS>

Type used to represent interned values.

type Output = &'a str

Type stored by the interner and made available with resolve.

fn resolve(self, symbol: Self::Input) -> Result<Self::Output>

Look up and return a reference to the value represented by a symbol, or an error if the symbol was not found.
