}

Fields§

§substitutions: Vec<Substitution>

Each substitute can have multiple variants due to multiple applicable suggestions

foo.bar might be replaced with a.b or x.y by replacing foo and bar on their own:

vec![
    Substitution { parts: vec![(0..3, "a"), (4..7, "b")] },
    Substitution { parts: vec![(0..3, "x"), (4..7, "y")] },
]

or by replacing the entire span:

vec![
    Substitution { parts: vec![(0..7, "a.b")] },
    Substitution { parts: vec![(0..7, "x.y")] },
]
§msg: DiagMessage§style: SuggestionStyle

Visual representation of this suggestion.

§applicability: Applicability

Whether or not the suggestion is approximate

Sometimes we may show suggestions with placeholders, which are useful for users but not useful for tools like rustfix
