Represents a single row from the database.

Required Associated Types

type Database: Database<Row = Self>

Required Methods

fn columns(&self) -> &[<Self::Database as Database>::Column]

Gets all columns in this statement.

Provided Methods

fn is_empty(&self) -> bool

Returns true if this row has no columns.

fn len(&self) -> usize

Returns the number of columns in this row.

fn column<I>(&self, index: I) -> &<Self::Database as Database>::Column

where I: ColumnIndex<Self>,

Gets the column information at index.

A string index can be used to access a column by name and a usize index can be used to access a column by position.

Panics

Panics if index is out of bounds. See try_column for a non-panicking version.

fn try_column<I>( &self, index: I, ) -> Result<&<Self::Database as Database>::Column, Error>

where I: ColumnIndex<Self>,

Gets the column information at index or None if out of bounds.

fn get<'a, T, I>(&'a self, index: I) -> T

where I: ColumnIndex<Self>, T: TryGetable<'a, Self::Database>,

Index into the database row and decode a single value.

A string index can be used to access a column by name and a usize index can be used to access a column by position.

Panics

Panics if the column does not exist or its value cannot be decoded into the requested type. See try_get for a non-panicking version.

fn try_get<'a, T, I>(&'a self, index: I) -> Result<T, Error>

where I: ColumnIndex<Self>, T: TryGetable<'a, Self::Database>,

Index into the database row and decode a single value.

A string index can be used to access a column by name and a usize index can be used to access a column by position.

Errors

• ColumnNotFound if the column by the given name was not found.
• ColumnIndexOutOfBounds if the usize index was greater than the number of columns in the row.
• ColumnDecode if the value could not be decoded into the requested type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
