Struct Pool 

pub struct Pool { /* private fields */ }

Values the records of one cache file share, each written once, by the digest of its text: a model’s faces, which every revision of the model that kept them holds alike.

Implementations

impl Pool

pub fn put<V: Serialize>(&mut self, value: &V) -> GeopResult<String>

Puts value, and gives what it is taken by (Pool::get).

pub fn get<V: DeserializeOwned>(&self, key: &str) -> GeopResult<V>

The value put as key.

pub fn shared<V: 'static>( &self, key: &str, read: impl FnOnce() -> GeopResult<V>, ) -> GeopResult<Rc<V>>

What read reads of the value put as key, read once for every record that reads it so: what many records hold alike — the drawing of a part placed a thousand times — is one value in memory. read reads the same of the same key, as a V.

pub fn len(&self) -> usize

How many values it holds.

pub fn is_empty(&self) -> bool

Whether it holds none.

Trait Implementations

impl Default for Pool

fn default() -> Pool

Returns the “default value” for a type.
