Trait NameMapIntern 

Source 
pub trait NameMapIntern {
    type Key: Borrow<Self::BorrowedKey>;
    type BorrowedKey: ?Sized + TryToOwned<Owned = Self::Key>;

    // Required methods
    fn intern(&mut self, s: &str) -> Result<Self::Key, OutOfMemory>;
    fn lookup<'a>(&'a self, s: &'a str) -> Option<TryCow<'a, Self::BorrowedKey>>;
}
Expand description

A helper trait used in conjunction with NameMap to optionally intern keys to non-strings.

Required Associated Types§

Source

type Key: Borrow<Self::BorrowedKey>

The key that this interning context generates.

Source

type BorrowedKey: ?Sized + TryToOwned<Owned = Self::Key>

The borrowed version of the key type.

Required Methods§

Source

fn intern(&mut self, s: &str) -> Result<Self::Key, OutOfMemory>

Inserts s into self and returns the intern’d key Self::Key.

Source

fn lookup<'a>(&'a self, s: &'a str) -> Option<TryCow<'a, Self::BorrowedKey>>

Looks up s in self returning Some if it was found or None if it’s not present.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
