Struct rustc_ap_rustc_errors::CodeSuggestion

pub struct CodeSuggestion {
    pub substitutions: Vec<Substitution>,
    pub msg: String,
    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: String

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

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

Returns the assembled code suggestions, whether they should be shown with an underline and whether the substitution only differs in capitalization.
