Struct Row

pub struct Row { /* private fields */ }

Implementations

impl Row

pub fn new( columns: &Arc<Vec<Column>>, column_names: &Arc<HashMap<String, usize>>, values: Box<[Value]>, ) -> Row

pub fn columns(&self) -> &Arc<Vec<Column>>

pub fn column_names(&self) -> &Arc<HashMap<String, usize>>

pub fn get<T>(&self, name: &str) -> Result<T, IntoTypedError>

where T: DeserializeOwned,

Get a value by column name

Errors

If the column name is not found, returns IntoTypedError::ColumnNotFound

pub fn get_opt<T>(&self, name: &str) -> Result<Option<T>, IntoTypedError>

where T: DeserializeOwned,

Get a value by column name, returning None if the value is null

Errors

If the column name is not found, returns IntoTypedError::ColumnNotFound

pub fn get_by_index<T>(&self, index: usize) -> Result<T, IntoTypedError>

where T: DeserializeOwned,

Get a value by index

Errors

If the index is out of bounds, returns IntoTypedError::ValueNotFound

pub fn get_by_index_opt<T>( &self, index: usize, ) -> Result<Option<T>, IntoTypedError>

where T: DeserializeOwned,

Get a value by index, returning None if the value is null

Errors

If the index is out of bounds, returns IntoTypedError::ValueNotFound

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

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn into_typed<T>(self) -> Result<T, IntoTypedError>

where T: FromRow,

Convert the row into a typed struct

Errors

If the conversion fails, returns IntoTypedError

Trait Implementations

impl Debug for Row

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

Formats the value using the given formatter.
