Implementations§

Source§

impl SchemaManager

Source

pub async fn load(path: impl AsRef<Path>) -> Result<Self>

Source

pub async fn load_from_store( store: Arc<dyn ObjectStore>, path: &ObjectStorePath, ) -> Result<Self>

Source

pub async fn save(&self) -> Result<()>

Source

pub fn path(&self) -> &ObjectStorePath

Source

pub fn schema(&self) -> Arc<Schema>

Source

pub fn generated_column_name(expr: &str) -> String

Generate a consistent internal column name for an expression index. Uses a hash suffix to ensure uniqueness for different expressions that might sanitize to the same string (e.g., “a+b” and “a-b” both become “a_b”).

IMPORTANT: Uses FNV-1a hash which is stable across Rust versions and platforms. DefaultHasher is not guaranteed to be stable and could break persistent data if the hash changes after a compiler upgrade.
