You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: suggest_name.rs
    path of file: ./repos/rust-analyzer/crates/ide-assists/src/utils
    
    the code of the file until where you have to start completion: //! This module contains functions to suggest names for expressions, functions and other items

use hir::Semantics;
use ide_db::{FxHashSet, RootDatabase};
use
    
fn from_field_name(expr: &ast::Expr) -> Option<String> {
    let field = match expr {
        ast::Expr::FieldExpr(field) => field,
        _ => return None,
    };
    let ident = field.name_ref()?.ident_token()?;
    normalize(ident.text())
}
