Enum rustc_middle::lint::LintLevelSource

pub enum LintLevelSource {
    Default,
    Node {
        name: Symbol,
        span: Span,
        reason: Option<Symbol>,
    },
    CommandLine(Symbol, Level),
}

How a lint level was set.

Variants

Default

Lint is at the default level as declared in rustc.

Node

Lint level was set by an attribute.

Fields

name: Symbol

span: Span

reason: Option<Symbol>

RFC 2383 reason

CommandLine(Symbol, Level)

Lint level was set by a command-line flag. The provided Level is the level specified on the command line. (The actual level may be lower due to --cap-lints.)

Implementations

impl LintLevelSource

pub fn name(&self) -> Symbol

pub fn span(&self) -> Span

Trait Implementations

impl Clone for LintLevelSource

fn clone(&self) -> LintLevelSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LintLevelSource

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

Formats the value using the given formatter.

impl<'__ctx> HashStable<StableHashingContext<'__ctx>> for LintLevelSource

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher, )

impl PartialEq for LintLevelSource

fn eq(&self, other: &LintLevelSource) -> 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.
