Struct Row 

pub struct Row { /* private fields */ }

A row of data from a query result.

Pre-computes column byte ranges for O(1) random access. Best for accessing multiple columns or accessing columns in random order.

Example

for row in client.query("SELECT id, name, active FROM users")? {
    let id = row.get_i32(0);
    let name = row.get_string(1);
    let active = row.get_bool(2);
    println!("{:?}: {:?} (active={:?})", id, name, active);
}

Implementations

impl Row

pub fn column_count(&self) -> usize

Returns the number of columns.

pub fn is_empty(&self) -> bool

Returns true if the row has no columns.

pub fn columns(&self) -> &[Column]

Returns the column metadata.

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

Returns 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 invalid format.

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

Gets an i32 value. Returns None if NULL or invalid format.

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

Gets an i64 value. Returns None if NULL or invalid format.

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

Gets an f32 value. Returns None if NULL or invalid format.

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

Gets an f64 value. Returns None if NULL or invalid format.

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

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

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

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

pub fn get_bytes_owned(&self, idx: usize) -> Option<Vec<u8>>

Gets raw bytes as owned Vec, decoding BYTEA hex format if needed.

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

Gets a typed value using the FromHyperBinary trait.

Returns None if the column is NULL or conversion fails.

pub fn get_by_name<T: FromHyperBinary>(&self, name: &str) -> Option<T>

Gets a typed value by column name.

Returns None if the column is NULL, not found, or conversion fails.

pub fn column_index(&self, name: &str) -> Result<usize>

Returns the index of a column by name.

Errors

Returns ErrorKind::Query with the column name in the message if no column matches.

Trait Implementations

impl Debug for Row

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
