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.

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.)

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
