FieldRef

Struct FieldRef 

Source
pub struct FieldRef {
    pub table: Option<NameKey>,
    pub name: NameKey,
}
Expand description

An unresolved field reference as written in DAX or in a report binding.

Holds the logical name: quote-unescaping (''') is the producer’s job — the DAX lexer or the PBIR parser — so 'Sales''s Data'[Amount] arrives here as the table name Sales's Data. Display re-applies the escaping.

Unresolved means the reference has not yet been bound to an ObjectId: [Total] could be a measure or a column of the current row context.

§Examples

use ripbi_core::{FieldRef, NameKey};

let qualified = FieldRef {
    table: Some(NameKey::new("Sales's Data")),
    name: NameKey::new("Amount"),
};
// Display re-applies DAX quoting, doubling the internal quote.
assert_eq!(qualified.to_string(), "'Sales''s Data'[Amount]");

let unqualified = FieldRef { table: None, name: NameKey::new("Total") };
assert_eq!(unqualified.to_string(), "[Total]");

Fields§

§table: Option<NameKey>

Qualifying table, if the reference was written qualified. 'Sales'[Amount]Some("Sales"); [Total]None.

§name: NameKey

The column or measure name inside the square brackets.

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

Source§

impl Display for FieldRef

Source§

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

Emits valid DAX. Table names are always single-quoted — quoting is optional in DAX only for names without spaces or punctuation, so quoting unconditionally is always correct. The bracketed part is not escaped: ] cannot appear in an Analysis Services object name, so there is nothing to escape.
