Enum rustc_middle::lint::LintLevelSource[−][src]

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

Expand description

How a lint level was set.

Variants

Default

Lint is at the default level as declared in rustc or a plugin.

Node(Symbol, Span, Option<Symbol>)

Lint level was set by an attribute.

Tuple Fields of Node

0: Symbol1: Span2: Option<Symbol>

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.)

Tuple Fields of CommandLine

0: Symbol1: Level

[src]

pub default fn fingerprint_style() -> FingerprintStyle

[src]

pub default fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous). Read more

[src]

pub default fn to_debug_str(&self, Ctxt) -> String

[src]

pub default fn recover(
Ctxt,
&DepNode<<Ctxt as DepContext>::DepKind>
) -> Option<T>

This method tries to recover the query key from the given DepNode, something which is needed when forcing DepNodes during red-green evaluation. The query system will only call this method if fingerprint_style() is not FingerprintStyle::Opaque. It is always valid to return None here, in which case incremental compilation will treat the query as having changed instead of forcing it. Read more
