Struct StringTable 

pub struct StringTable { /* private fields */ }

Holds unique strings and provides StringIds that correspond to the order that the strings were inserted.

Implementations

impl StringTable

pub fn new() -> Self

Creates a new string table, which initially holds the empty string and no others.

pub fn len(&self) -> usize

Returns the number of strings currently held in the string table.

pub fn intern(&mut self, str: &str) -> StringId

Adds the string to the string table if it isn’t present already, and returns a StringId that corresponds to the order that this string was originally inserted.

Panics

Panics if an allocator fails, or if the number of strings would exceed u32::MAX.

pub fn try_intern(&mut self, str: &str) -> Result<StringId, Error>

Adds the string to the string table if it isn’t present already, and returns a StringId that corresponds to the order that this string was originally inserted.

Fails if an allocator fails, or if the number of strings would exceed u32::MAX.
