Struct Row 

pub struct Row { /* private fields */ }

One row read with SELECT *, columns in table order.

Implementations

impl Row

pub fn new(columns: Vec<String>, values: Vec<Value>) -> Self

A row with these columns and values (same length and order).

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

Column names, in table order.

pub fn values(&self) -> &[Value]

Values, in column order.

pub fn iter(&self) -> impl Iterator<Item = (&str, &Value)>

(column, value) pairs in table order.

pub fn get(&self, column: &str) -> Option<&Value>

The value of a column; None when the table has no such column.

pub fn has(&self, column: &str) -> bool

The column exists in this row’s table (it may still be NULL).

pub fn is_set(&self, column: &str) -> bool

Not NULL and present.

pub fn int(&self, column: &str) -> i64

Integer value; NULL, missing and non-numeric read as 0.

pub fn opt_int(&self, column: &str) -> Option<i64>

Integer value (reals are truncated); None when NULL, missing or not a number.

pub fn real(&self, column: &str) -> f64

Real value; NULL, missing and non-numeric read as 0.0.

pub fn opt_real(&self, column: &str) -> Option<f64>

Real value (integers converted); None when NULL, missing or not a number.

pub fn text(&self, column: &str) -> Option<String>

Text value; UTF-8 blobs are decoded too. None when NULL or missing.

pub fn blob(&self, column: &str) -> Option<&[u8]>

Blob value (text as its UTF-8 bytes); None when NULL or missing.

pub fn truthy(&self, column: &str) -> bool

A value that is not NULL, 0 or empty.

pub fn set(&mut self, column: &str, value: Value) -> bool

Replace a value (the column must exist).

impl Default for Row

fn default() -> Self

Returns the “default value” for a type.
