Struct Lookuper 

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

Performs key-based lookups against a primary key table.

The Lookuper automatically encodes the lookup key, computes the target bucket, finds the appropriate tablet server, and retrieves the value.

§Example

ⓘ
let lookuper = table.new_lookup()?.create_lookuper()?;
let row = GenericRow::new(vec![Datum::Int32(42)]); // lookup key
let result = lookuper.lookup(&row).await?;

Implementations§

Source§

impl Lookuper

Source

pub async fn lookup(&mut self, row: &dyn InternalRow) -> Result<LookupResult>

Looks up a value by its primary key.

The key is encoded and the bucket is automatically computed using the table’s bucketing function.

§Arguments
  • row - The row containing the primary key field values
§Returns
  • Ok(LookupResult) - The lookup result (may be empty if key not found)
  • Err(Error) - If the lookup fails
Source

pub fn table_info(&self) -> &TableInfo

Returns a reference to the table info.
