Struct rustc_errors::CodeSuggestion

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

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>, Vec<Vec<SubstitutionHighlight>>, bool)>

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

Trait Implementations

impl Clone for CodeSuggestion

fn clone(&self) -> CodeSuggestion

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CodeSuggestion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for CodeSuggestion

fn decode(__decoder: &mut __D) -> Self

impl<__E: Encoder> Encodable<__E> for CodeSuggestion

fn encode(&self, __encoder: &mut __E)

impl Hash for CodeSuggestion

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<CodeSuggestion> for CodeSuggestion

fn eq(&self, other: &CodeSuggestion) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
