FstBlockIndex

Struct FstBlockIndex 

Source
pub struct FstBlockIndex { /* private fields */ }
Expand description

FST-based block index (Option 1)

Maps keys to block ordinals using an FST. The FST bytes can be mmap’d directly without any parsing or heap allocation.

Implementations§

Source§

Source

pub fn load(data: OwnedBytes) -> Result<Self>

Load from raw bytes

Source

pub fn locate(&self, key: &[u8]) -> Option<usize>

Look up the block index for a key Returns the block ordinal that could contain this key

Source

pub fn get_addr(&self, ordinal: usize) -> Option<BlockAddr>
