Enum Category 

pub enum Category {
    UnusedFile,
    UnusedExport,
    UnusedSymbol,
    UnusedImport,
    UnusedMember,
}

A class of finding. Every category can be switched off independently because they carry very different false-positive rates: unused imports are nearly always safe to act on, unused class members in a dynamic codebase are not.

Variants

UnusedFile

A file no entry point reaches through the import graph.

UnusedExport

An exported name that no reachable module imports.

UnusedSymbol

A module-private declaration with no references in its own module.

UnusedImport

An import binding with no references.

UnusedMember

A class member or enum member nothing appears to access.

Implementations

impl Category

pub const ALL: &'static [Category]

pub const DEFAULT: &'static [Category]

The default set: every category except members, whose accuracy depends most on type information basta does not have.

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

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

Heading used when grouping findings for a human reader.

Trait Implementations

impl Clone for Category

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Category

impl Debug for Category

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

Formats the value using the given formatter.

impl Eq for Category

impl FromStr for Category

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Category

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 Category

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Category

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Category

fn partial_cmp(&self, other: &Self) -> 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
