Expand description
A Rust literal such as a string or integer or boolean.
§Syntax tree enum
This type is a syntax tree enum.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Str(LitStr)
A UTF-8 string literal: "foo"
.
ByteStr(LitByteStr)
A byte string literal: b"foo"
.
Byte(LitByte)
A byte literal: b'f'
.
Char(LitChar)
A character literal: 'a'
.
Int(LitInt)
An integer literal: 1
or 1u16
.
Float(LitFloat)
A floating point literal: 1f64
or 1.0e10f64
.
Must be finite. May not be infinite or NaN.
Bool(LitBool)
A boolean literal: true
or false
.
Verbatim(Literal)
A raw token literal not interpreted by Syn.
