Enum Check 

#[non_exhaustive]
pub enum Check {
    InvalidIdentifier,
    InvalidPackage,
    DuplicateType,
    DuplicateValue,
    DuplicateFunction,
    DuplicateRaw,
    PropertyWithoutTypeOrValue,
    EnumEntryMissingArguments,
    FunctionWithoutBody,
    ImportCollision,
}

Which check produced a Diagnostic.

Consumers match on this to override a severity, so it is the stable name of a check rather than its message.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidIdentifier

A declared name is not something Kotlin can write.

InvalidPackage

A file’s package is not a legal Kotlin package path.

DuplicateType

Two type declarations in one scope share a name — classes, fun interfaces and type aliases all live in Kotlin’s classifier namespace.

DuplicateValue

Two value declarations in one scope share a name — properties and val/var constructor parameters.

DuplicateFunction

Two functions in one scope share a name and a parameter type list. Same-named functions with different parameters are overloads and pass.

DuplicateRaw

Two Raw blocks in one scope share a name. Identical ones are merged rather than reported (see merge_files), so this means two different blocks are claiming one identity.

PropertyWithoutTypeOrValue

A property has no type, no value and no accessors — val x alone, which is never legal.

EnumEntryMissingArguments

An enum class declares primary-constructor parameters, but an entry passes no arguments.

FunctionWithoutBody

A function has no body somewhere a bodiless function is not allowed.

ImportCollision

Two distinct FQNs referenced from raw text share a simple name, so the text cannot be made to refer to both.

Implementations

impl Check

pub const ALL: &'static [Check]

Every check, so a policy can be built over all of them. Adding a check extends this list, which is what keeps ValidationPolicy::warn_all correct as the set grows.

pub fn name(self) -> &'static str

The stable, greppable name of this check.

Trait Implementations

impl Clone for Check

fn clone(&self) -> Check

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Check

impl Debug for Check

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

Formats the value using the given formatter.

impl Display for Check

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

Formats the value using the given formatter.

impl Eq for Check

impl Hash for Check

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 Ord for Check

fn cmp(&self, other: &Check) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Check

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Check

fn partial_cmp(&self, other: &Check) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
