}Expand description
A generic interface over any underlying interner, allowing storing and accessing interned strings
Note that because single-threaded Rodeos require mutable access to use, this
trait does so as well. For use with ThreadedRodeo, the trait is
implemented for &ThreadedRodeo as well to allow access through shared references.
Required Methods§
sourcefn get_or_intern(&mut self, val: &str) -> K
fn get_or_intern(&mut self, val: &str) -> K
Get the key for a string, interning it if it does not yet exist
Panics
Panics if the key’s try_from_usize function fails. With the default
keys, this means that you’ve interned more strings than it can handle. (For Spur this
means that u32::MAX - 1 unique strings were interned)
sourcefn try_get_or_intern(&mut self, val: &str) -> LassoResult<K>
fn try_get_or_intern(&mut self, val: &str) -> LassoResult<K>
Get the key for a string, interning it if it does not yet exist
sourcefn get_or_intern_static(&mut self, val: &'static str) -> K
fn get_or_intern_static(&mut self, val: &'static str) -> K
Get the key for a static string, interning it if it does not yet exist
This will not reallocate or copy the given string
Panics
Panics if the key’s try_from_usize function fails. With the default
keys, this means that you’ve interned more strings than it can handle. (For Spur this
means that u32::MAX - 1 unique strings were interned)
sourcefn try_get_or_intern_static(&mut self, val: &'static str) -> LassoResult<K>
fn try_get_or_intern_static(&mut self, val: &'static str) -> LassoResult<K>
Get the key for a static string, interning it if it does not yet exist
This will not reallocate or copy the given string
