Variants

Ident

An identifier: mnemonic, register name, or label reference.

Number(i128)

A numeric literal (integer).

StringLit

A string literal (content without quotes).

CharLit(u8)

A character literal (e.g., ‘A’).

Directive

A directive (starts with .).

LabelDef

Label definition (name:).

NumericLabelDef(u32)

Numeric label definition (1:).

NumericLabelFwd(u32)

Numeric label forward reference (1f).

NumericLabelBwd(u32)

Comma

Comma separator.

OpenBracket

Open bracket [.

CloseBracket

Close bracket ].

Plus

Plus +.

Minus

Minus -.

Star

Asterisk * (for scale in memory operands).

Colon

Colon : (segment override: fs:).

Equals

Equals = (constant assignment: name = value).

OpenBrace

Forward slash / (SVE predicate qualifier: p0/m, p0/z).

Ampersand

Ampersand & (bitwise AND in constant expressions).

Pipe

Pipe | (bitwise OR in constant expressions).

Caret

Caret ^ (bitwise XOR in constant expressions).

A newline (statement separator).

Eof

End of input.

Trait Implementations

impl Clone for TokenKind

fn clone(&self) -> TokenKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenKind

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

Formats the value using the given formatter.

impl PartialEq for TokenKind

fn eq(&self, other: &TokenKind) -> 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.
