Struct HashIndex 

pub struct HashIndex {
    pub by_content: FxHashMap<String, Vec<u32>>,
    pub by_lang: FxHashMap<String, Vec<u32>>,
    pub by_depth: FxHashMap<u8, Vec<u32>>,
}

Hash index for point-equality lookups on string/integer columns.

Covers content (exact match), lang (code language), and heading depth.

Best for: WHERE content = 'Architecture', WHERE lang = 'rust', WHERE depth = 2
Complexity: build O(n), lookup O(1) average

Fields

by_content: FxHashMap<String, Vec<u32>>

content (exact lowercase) → block indices

by_lang: FxHashMap<String, Vec<u32>>

lang tag → block indices (code blocks only)

by_depth: FxHashMap<u8, Vec<u32>>

heading depth → block indices

Implementations

impl HashIndex

pub fn build(blocks: &[Block]) -> Self

pub fn by_content(&self, content: &str) -> &[u32]

Exact content match (case-insensitive). O(1).

pub fn by_lang(&self, lang: &str) -> &[u32]

Exact lang match. O(1).

pub fn by_depth(&self, depth: u8) -> &[u32]

Heading depth lookup. O(1).

Trait Implementations

impl Clone for HashIndex

fn clone(&self) -> HashIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HashIndex

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

Formats the value using the given formatter.

impl Default for HashIndex

fn default() -> HashIndex

Returns the “default value” for a type.
