Struct StreamRow 

pub struct StreamRow { /* private fields */ }

A streaming row optimized for sequential single-pass access.

Unlike Row, this computes column offsets on-demand without pre-allocation. Best for high-throughput scans where each row is processed once.

Example

// High-throughput streaming access
let mut stream = client.query_streaming("SELECT id, value FROM sensors", 1000)?;
while let Some(chunk) = stream.next_chunk()? {
    for row in chunk {
        if let Some(id) = row.get_i32(0) {
            process(id, row.get_f64(1));
        }
    }
}

Implementations

impl StreamRow

pub fn column_count(&self) -> usize

Returns the number of columns.

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

Gets raw bytes for a column, or None if NULL.

pub fn is_null(&self, idx: usize) -> bool

Returns true if the column is NULL.

pub fn get_i16(&self, idx: usize) -> Option<i16>

Gets an i16 value. Returns None if NULL or wrong size.

pub fn get_i32(&self, idx: usize) -> Option<i32>

Gets an i32 value. Returns None if NULL or wrong size.

pub fn get_i64(&self, idx: usize) -> Option<i64>

Gets an i64 value. Returns None if NULL or wrong size.

pub fn get_f32(&self, idx: usize) -> Option<f32>

Gets an f32 value. Returns None if NULL or wrong size.

pub fn get_f64(&self, idx: usize) -> Option<f64>

Gets an f64 value. Returns None if NULL or wrong size.

pub fn get_bool(&self, idx: usize) -> Option<bool>

Gets a bool value. Returns None if NULL or invalid.

pub fn get_string(&self, idx: usize) -> Option<String>

Gets a String value. Returns None if NULL or invalid UTF-8.

pub fn get<T: FromBinaryValue>(&self, idx: usize) -> Option<T>

Generic typed getter with automatic type coercion.

Supports widening conversions (i16 → i32 → i64, f32 → f64).

pub fn to_batch(self) -> BatchRow

Converts to a BatchRow with pre-computed offsets for multi-column access.

pub fn into_data(self) -> DataRowBody

Returns the underlying DataRowBody (for advanced use).
