Expand description
Literal kind.
E.g., "foo"
, 42
, 12.34
, or bool
.
Variants
A string literal ("foo"
).
A byte string (b"foo"
).
Byte(u8)
A byte char (b'f'
).
Char(char)
A character literal ('a'
).
Int(u128, LitIntType)
An integer literal (1
).
Float(Symbol, LitFloatType)
A float literal (1f64
or 1E10f64
).
Bool(bool)
A boolean literal.
Err(Symbol)
Placeholder for a literal that wasn’t well-formed in some way.
Implementations
Attempts to recover a token from semantic literal. This function is used when the original token doesn’t exist (e.g. the literal is created by an AST-based macro) or unavailable (e.g. from HIR pretty-printing).
Returns true
if this literal is byte literal string.
Returns true
if this is a numeric literal.
Returns true
if this literal has no suffix.
Note: this will return true for literals with prefixes such as raw strings and byte strings.
Returns true
if this literal has a suffix.
