[−][src]Struct bio_types::annot::refids::RefIDSet
Data structure for interning sequence names efficiently.
The structure is parameterized over the reference type R
used to
intern strings. Typically, this would be Rc
for single-threaded
access or Arc
for multi-threaded access. These reference types
provide fast, reference-counted cloning with no new allocation,
which can make sequence location calculations faster as well as
reducing the memory footprint required.

Methods
impl<R> RefIDSet<R>
[src]
pub fn new() -> Self
[src]
Create a new, empty table of interned reference names
pub fn intern(&mut self, id: &str) -> R where
R: Deref<Target = String> + From<String> + Clone,
[src]
R: Deref<Target = String> + From<String> + Clone,
Intern a reference name.
This returns a shared reference of type R
for the name. This
reference will be shared with any other intern calls for the
same name. The name is given originally as a reference, and it
will be cloned into an owned String
only when the name is
new for the data type.
