Enum AttrValue 

pub enum AttrValue {
    String(String),
    Int(u64),
    ByteList(Vec<u8>),
    Flag,
}

Right-hand side of an attribute. Kept small on purpose — every new variant has to round-trip through emit + parse + lower.

Variants

String(String)

"…" — quoted string.

Int(u64)

0x… or decimal integer.

ByteList(Vec<u8>)

[0x01, 0x02, …] — used by head_bytes and friends.

Flag

Bare flag, e.g. #[naked] — no =value part. Renders as just the key name; parses from any attribute that omits the = sign.

Trait Implementations

impl Clone for AttrValue

fn clone(&self) -> AttrValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttrValue

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

Formats the value using the given formatter.

impl PartialEq for AttrValue

fn eq(&self, other: &AttrValue) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
