Struct Column 

pub struct Column {
    pub key: Option<Arc<str>>,
    pub source_key: Option<Arc<str>>,
    pub format: Format,
    pub default: Option<Value>,
    pub date_only: bool,
    pub decimal_comma: bool,
}

Fields

key: Option<Arc<str>>

source_key: Option<Arc<str>>

Natural (auto-detected, snake_cased) key to match this override against, regardless of the column’s actual position. When None, the column applies positionally instead (matched by its index within the configured column list), as before.

format: Format

default: Option<Value>

date_only: bool

decimal_comma: bool

Implementations

impl Column

pub fn new(key_opt: Option<&str>) -> Self

build new column with an optional key name only

pub fn new_format(fmt: Format, default: Option<Value>) -> Self

build new column data type override and optional default

pub fn from_source_key_with_format( source_key: &str, key_opt: Option<&str>, format: Format, default: Option<Value>, date_only: bool, decimal_comma: bool, ) -> Self

build a column override matched by its natural (auto-detected) key rather than by position, e.g. to rename and/or reformat a single field out of many without needing to enumerate every column ahead of it.

pub fn from_json(json: &Value) -> Self

build new column data type override and optional default

pub fn set_format(self, fmt: Format) -> Self

pub fn set_default(self, val: Value) -> Self

pub fn set_date_only(self, val: bool) -> Self

pub fn set_decimal_comma(self, val: bool) -> Self

pub fn from_key_ref_with_format( key_opt: Option<&str>, format: Format, default: Option<Value>, date_only: bool, decimal_comma: bool, ) -> Self

pub fn key_name(&self) -> String

pub fn source_key_name(&self) -> String

pub fn to_json(&self) -> Value

pub fn to_line(&self) -> String
