Enum ShouldEmit 

pub enum ShouldEmit {
    EarlyFatal {
        also_emit_lints: bool,
    },
    ErrorsAndLints {
        recover: bool,
    },
    Nothing,
}

Variants

EarlyFatal

The operations will emit errors, and lints, and errors are fatal.

Only relevant when early parsing, in late parsing equivalent to ErrorsAndLints. Late parsing is never fatal, and instead tries to emit as many diagnostics as possible.

Fields

also_emit_lints: bool

ErrorsAndLints

The operation will emit errors and lints. This is usually what you need.

Fields

recover: bool

Whether ArgParser will attempt to recover from errors.

If true, it will attempt to recover from bad input (like an invalid literal). Setting this to false will instead return early, and not raise errors except at the top level (in ArgParser::from_attr_args).

Nothing

The operation will not emit errors and lints.

The parser can still call delay_bug, so you must ensure that this operation will also be called with ShouldEmit::ErrorsAndLints.

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.
