pub struct Column {
    pub name: String,
    pub column_type: ValueType,
    pub limiter: ValueLimiter,
}

Fields

name: String

column_type: ValueType

limiter: ValueLimiter

Implementations

impl Column

pub fn empty(name: &str) -> Self

Create empty column with name

pub fn new( name: &str, column_type: ValueType, limiter: Option<ValueLimiter>, ) -> Self

Create new column with properties

pub fn get_name(&self) -> &str

Get column name

pub fn get_column_type(&self) -> &ValueType

Get column type

pub fn rename(&mut self, new_name: &str) -> String

pub fn set_limiter(&mut self, limiter: ValueLimiter)

Apply limiter to a column

pub fn get_default_value(&self) -> Value

Every value type has it’s own default value. The default value can differ by limiter’s variant of patterns and should comply to a limter’s predicate.
