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
Expand description

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

Node(Symbol, Span, Option<Symbol>)
Expand description

Lint level was set by an attribute.

CommandLine(Symbol, Level)
Expand description

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.)
