NameKey

Struct NameKey 

Source
pub struct NameKey { /* private fields */ }
Expand description

An object name that compares, hashes, and orders case-insensitively while preserving the original casing for display.

The folded form is computed once at construction, so equality and hashing are plain string operations on a precomputed field.

std::borrow::Borrow<str> is deliberately not implemented: Borrow requires that the borrowed value hash and compare identically to the owner, which cannot hold when Eq/Hash use folded while as_str yields original.

§Examples

use ripbi_core::NameKey;

// Case is irrelevant to identity, in ASCII and beyond.
assert_eq!(NameKey::new("Sales"), NameKey::new("SALES"));
assert_eq!(NameKey::new("MÅNED"), NameKey::new("måned"));

// ...but the model's own casing survives for display.
assert_eq!(NameKey::new("SaLeS").as_str(), "SaLeS");

Implementations§

Source§

impl NameKey

Source

pub fn new(name: impl Into<String>) -> Self

Creates a key from a name as written in the source model.

Source

pub fn as_str(&self) -> &str

The name with its original casing, as written in the source model.

Source

pub fn folded(&self) -> &str

The case-folded form used for equality, hashing, and ordering.

Source

pub fn quoted(&self) -> impl Display + '_

Writes the name as a single-quoted DAX identifier, doubling any internal quote — the same form ObjectId and FieldRef display table names in.

§Examples
use ripbi_core::NameKey;

assert_eq!(NameKey::new("Sales").quoted().to_string(), "'Sales'");
assert_eq!(NameKey::new("O'Brien").quoted().to_string(), "'O''Brien'");

impl Ord for NameKey

Source§
