Struct dcsv::Row

pub struct Row {
    pub values: HashMap<String, Value>,
}

Row

Row is implementated as a hashmap. You cannot iterate row without column information.

Fields

values: HashMap<String, Value>

Implementations

impl Row

pub fn new() -> Self

Create a new row

pub fn to_vector(&self, columns: &[Column]) -> DcsvResult<Vec<&Value>>

Convert row to vector with given columns

It is totally valid to give partial columns into a row.

pub fn to_string(&self, columns: &[Column]) -> DcsvResult<String>

Get comma separated row string

This requires columns because a row is not a linear container. Partial column is not an error but valid behaviour.

pub fn rename_column(&mut self, name: &str, new_name: &str)

Rename column name inside row map

This doesn’t validate column’s name and should comply with column name rule to avoid unintended behaviour.

pub fn insert_cell(&mut self, key: &str, value: Value)

Insert a new cell(key, value pair) into a row

pub fn get_cell_value(&self, key: &str) -> Option<&Value>

Get a cell value by a key

pub fn update_cell_value(&mut self, key: &str, value: Value)

Update a cell’s value with a given value

This doesn’t fail and silently do nothing if key doesn’t exist.

pub fn change_cell_type(
    &mut self,
    key: &str,
    target_type: ValueType
) -> DcsvResult<()>

Chagnes a cell’s value type

This method tries to naturally convert cell’s type. Empty text value defaults to “0”.

pub fn remove_cell(&mut self, key: &str)

Remove a cell by key

pub fn get_iterator(&self, columns: &[Column]) -> IntoIter<&Value>

Get iterator with given columns

Trait Implementations

impl Clone for Row

fn clone(&self) -> Row

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Row

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

Formats the value using the given formatter.

impl Default for Row

fn default() -> Self

Returns the “default value” for a type.
