Struct dcsv::ValueLimiter

pub struct ValueLimiter { /* private fields */ }

Limiter that costraints which data that Value can hold

VaulueLimiter has four properties

• type ( Eitehr number or text )
• default value
• variants ( Range of values )
• pattern ( Regex pattern )

Implementations

impl ValueLimiter

pub fn is_convertible(&self, value: &Value) -> Option<ValueType>

Check if given value can be converted to the type of valuelimiter

pub fn qualify(&self, value: &Value) -> bool

Check if value qualifies

pub fn from_line(attributes: &[impl AsRef<str>]) -> DcsvResult<Self>

Create value limiter from attributes

The order is

• Type
• Default
• Variant
• Pattern

pub fn get_type(&self) -> ValueType

Get type

pub fn set_type(&mut self, column_type: ValueType)

Set type

pub fn get_default(&self) -> Option<&Value>

Get default value from limiter

pub fn get_variant(&self) -> Option<&Vec<Value>>

Return variant reference

pub fn set_variant( &mut self, default: Value, variants: &[Value] ) -> DcsvResult<()>

Set variant

pub fn get_pattern(&self) -> Option<&Regex>

Get pattern

pub fn set_pattern(&mut self, default: Value, pattern: Regex) -> DcsvResult<()>

Set pattern
