Function extract_trailing_identifier

src/inlay_hints.rs:497–508

Extract the trailing identifier from a member-access expression. For `$this->foo->bar`, returns `"bar"`. For `SomeClass::method`, returns `"method"`.

(text: &str)

/// For `$this->foo->bar`, returns `"bar"`.
/// For `SomeClass::method`, returns `"method"`.
fn extract_trailing_identifier(text: &str) -> Option<&str> {
    let trimmed = text.trim();
    // Look for `->identifier` or `::identifier` at the end.
    let pos = trimmed.rfind("->").or_else(|| trimmed.rfind("::"))?;
    let after = &trimmed[pos + 2..];
    // The trailing part should be a simple identifier.
    if after.chars().all(|c| c.is_alphanumeric() || c == '_') && !after.is_empty() {
        Some(after)
    } else {
        None
    }
}

/// Compare two identifiers ignoring case and treating snake_case
/// as equivalent to camelCase.
