Enum rustc_lint_defs::Applicability

pub enum Applicability {
    MachineApplicable,
    MaybeIncorrect,
    HasPlaceholders,
    Unspecified,
}

Indicates the confidence in the correctness of a suggestion.

All suggestions are marked with an Applicability. Tools use the applicability of a suggestion to determine whether it should be automatically applied or if the user should be consulted before applying the suggestion.

Variants

MachineApplicable

The suggestion is definitely what the user intended, or maintains the exact meaning of the code. This suggestion should be automatically applied.

In case of multiple MachineApplicable suggestions (whether as part of the same multipart_suggestion or not), all of them should be automatically applied.

MaybeIncorrect

The suggestion may be what the user intended, but it is uncertain. The suggestion should result in valid Rust code if it is applied.

HasPlaceholders

The suggestion contains placeholders like (...) or { /* fields */ }. The suggestion cannot be applied automatically because it will not result in valid Rust code. The user will need to fill in the placeholders.

Unspecified

The applicability of the suggestion is unknown.

Trait Implementations

impl Clone for Applicability

fn clone(&self) -> Applicability

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Applicability

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

Formats the value using the given formatter.

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

fn decode(__decoder: &mut __D) -> Result<Self, <__D as Decoder>::Error>

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

fn encode(&self, __encoder: &mut __E) -> Result<(), <__E as Encoder>::Error>

impl Hash for Applicability

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, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<Applicability> for Applicability

fn eq(&self, other: &Applicability) -> 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 !=.

impl Copy for Applicability

impl StructuralPartialEq for Applicability

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.
