Struct rustc_errors::CodeSuggestion

pub struct CodeSuggestion {
    pub substitutions: Vec<Substitution>,
    pub msg: DiagMessage,
    pub style: SuggestionStyle,
    pub applicability: Applicability,
}

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

Implementations§

impl CodeSuggestion

source

pub(crate) fn splice_lines( &self, sm: &SourceMap, ) -> Vec<(String, Vec<SubstitutionPart>, Vec<Vec<SubstitutionHighlight>>, bool)>
