Struct ConnectionCosts 

pub struct ConnectionCosts<'a> {
    pub left_size: usize,
    pub right_size: usize,
    pub data_offset: usize,
    pub data: &'a [u8],
}

Bundled connection cost lookup: matrix metadata + backing data slice. Used by the lattice and tokenizer hot path to avoid passing two separate arguments.

Fields

left_size: usize

right_size: usize

data_offset: usize

data: &'a [u8]

Implementations

impl<'a> ConnectionCosts<'a>

pub fn new(matrix: &ConnectionMatrix, data: &'a [u8]) -> Self

Create from a ConnectionMatrix and its backing data.

pub fn get_cost(&self, left_id: i16, right_id: i16) -> i16

Look up connection cost between a left ID and right ID. Returns INHIBITED_CONNECTION (0x7fff) if the index is out of bounds.

Trait Implementations

impl<'a> Clone for ConnectionCosts<'a>

fn clone(&self) -> ConnectionCosts<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ConnectionCosts<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
