Enum RawRef 

pub enum RawRef<'a> {
    Field {
        table: Option<&'a str>,
        name: &'a str,
        span: Range<usize>,
    },
    Table {
        name: &'a str,
        span: Range<usize>,
    },
    Function {
        name: &'a str,
        span: Range<usize>,
    },
}

One object reference found in an expression, exactly as written.

Names are raw source slices: delimiters are stripped, but quote escapes are left intact ('It''s' yields "It''s"). unescape_name and RawRef::to_field_ref produce the logical names that FieldRef and the rest of the identity layer expect.

Extraction is purely syntactic and knows nothing about any model: whether a bracketed name is a column or a measure, and whether an identifier names a real table or function at all, is decided by resolution, not here.

Variants

Field

A column or measure reference: 'Table'[Name], Table[Name], or an unqualified [Name]. table is None exactly when the reference was written unqualified.

Fields

table: Option<&'a str>

Qualifying table name as written, delimiters stripped.

name: &'a str

The name inside the brackets, as written.

span: Range<usize>

Byte range of the whole reference, qualifier included.

Table

A bare table use: COUNTROWS(Sales), EVALUATE Sales. Detected so that a table referenced only this way is never reported unused.

Fields

name: &'a str

The table name as written, delimiters stripped.

span: Range<usize>

Byte range of the name.

Function

A function call: an identifier followed by (. Whether this is a user-defined function of the model (a real dependency) or a built-in (SUM, COUNTROWS, …) is decided by resolution.

Fields

name: &'a str

The function name as written.

span: Range<usize>

Byte range of the name.

Implementations

impl RawRef<'_>

pub fn to_field_ref(&self) -> Option<FieldRef>

The logical FieldRef of a RawRef::Field — delimiters stripped and quote escapes resolved, per the identity layer’s producer contract. None for RawRef::Table and RawRef::Function, which name no column or measure.
