error unknown-field

What it means#

The field name does not exist in the data type, in its embedded types (§4.7), or among the variant fields of the enum (§4.2, §4.4). It is reported for field access, for struct literals and for patterns.

Example#

data User {
  id: u64
  name: str
}

fn main() {
  let u = User{ id: 1, name: "Ann" }
  print(u.nmae)      // <- unknown-field
}

unknown-field

How to fix#

data User {
  id: u64
  name: str
}

fn main() {
  let u = User{ id: 1, name: "Ann" }
  print(u.name)
}

Correct the name, or add the field to the type.
