Struct Row

pub struct Row { /* private fields */ }

A row.

Implementations

impl Row

pub fn contains<T>(&self, column: T) -> bool

where T: RowIndex,

Check if the row contains a column.

In case of integer indices, the first column has index 0.

pub fn read<'l, T, U>(&'l self, column: U) -> T

where T: TryFrom<&'l Value, Error = Error>, U: RowIndex,

Read the value in a column.

In case of integer indices, the first column has index 0.

Panics

Panics if the column can not be read.

pub fn take<U>(&mut self, column: U) -> Value

where U: RowIndex,

Take the value from a column.

In case of integer indices, the first column has index 0. Any subsequent invocation will result in Value::Null.

pub fn try_read<'l, T, U>(&'l self, column: U) -> Result<T>

where T: TryFrom<&'l Value, Error = Error>, U: RowIndex,

Try to read the value in a column.

In case of integer indices, the first column has index 0.

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

Iterate over the names and values.

Trait Implementations

impl Debug for Row

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

Formats the value using the given formatter.

impl From<Row> for Vec<Value>

fn from(row: Row) -> Self

Converts to this type from the input type.

impl<T> Index<T> for Row

where T: RowIndex,

type Output = Value

The returned type after indexing.

fn index(&self, index: T) -> &Value

Performs the indexing (container[index]) operation.
