Struct UnsyncStringSet 

pub struct UnsyncStringSet(/* private fields */);

Holds unique strings and provides StringRefs to fetch them later. This is a newtype around SliceSet to enforce UTF-8 invariants.

Implementations

impl UnsyncStringSet

pub fn try_with_capacity(capacity: usize) -> Result<Self, SetError>

pub fn try_new() -> Result<Self, SetError>

Creates a new string set, which initially holds the empty string and other well-known strings. The well-known strings are always available and can be fetched using the WELL_KNOWN_STRING_REFS.

pub unsafe fn insert_unique_uncontended( &mut self, str: &str, ) -> Result<StringRef, SetError>

Safety

1. The hash must be the same as if the str was re-hashed with the hasher the string set would use.
2. The string must be unique within the set.

pub unsafe fn insert_unique_uncontended_with_hash( &mut self, hash: u64, str: &str, ) -> Result<StringRef, SetError>

Inserts a string into the string set without checking for duplicates, using a pre-calculated hash.

Safety

1. The caller must ensure that the hash was computed using the same hasher the string set would use.
2. The string must be unique within the set.

pub fn try_insert(&mut self, str: &str) -> Result<StringRef, SetError>

Adds the string to the string set if it isn’t present already, and returns a handle to the string that can be used to retrieve it later.

pub unsafe fn try_insert_with_hash( &mut self, hash: u64, str: &str, ) -> Result<StringRef, SetError>

Adds the string to the string set if it isn’t present already, using a pre-calculated hash. Returns a handle to the string that can be used to retrieve it later.

Safety

The caller must ensure that the hash was computed using the same hasher the string set would use.

pub fn string_ids(&self) -> impl Iterator<Item = StringRef> + '_

Returns an iterator over all strings in the set as StringRefs.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn capacity(&self) -> usize

pub unsafe fn get_string(&self, id: StringRef) -> &str

Safety

The caller must ensure that the StringId was obtained from this set (or is a well-known id) and that the set outlives the returned &str.
