Struct CompactSchema 

pub struct CompactSchema { /* private fields */ }

Compact representation of a symbol table.

Uses string interning and delta encoding to minimize size.

Implementations

impl CompactSchema

pub fn from_symbol_table(table: &SymbolTable) -> Self

Create a compact schema from a symbol table.

Example

use tensorlogic_adapters::{SymbolTable, DomainInfo, CompactSchema};

let mut table = SymbolTable::new();
table.add_domain(DomainInfo::new("Person", 100)).unwrap();

let compact = CompactSchema::from_symbol_table(&table);
let recovered = compact.to_symbol_table().unwrap();

assert_eq!(table.domains.len(), recovered.domains.len());

pub fn to_symbol_table(&self) -> Result<SymbolTable>

Convert compact schema back to a symbol table.

pub fn to_binary(&self) -> Result<Vec<u8>>

Serialize to compact binary format.

pub fn from_binary(data: &[u8]) -> Result<Self>

Deserialize from compact binary format.

pub fn string_count(&self) -> usize

Get the number of unique strings.

pub fn compression_stats(&self) -> CompressionStats

Get statistics about compression.
