Enum syn::Lit
[−]
[src]
pub enum Lit { Str(LitStr), ByteStr(LitByteStr), Byte(LitByte), Char(LitChar), Int(LitInt), Float(LitFloat), Bool(LitBool), Verbatim(LitVerbatim), }
A Rust literal such as a string or integer or boolean.
This type is available if Syn is built with the "derive"
or "full"
feature.
Syntax tree enum
This type is a syntax tree enum.
Variants
Str(LitStr)
A UTF-8 string literal: "foo"
.
This type is available if Syn is built with the "derive"
or
"full"
feature.
ByteStr(LitByteStr)
A byte string literal: b"foo"
.
This type is available if Syn is built with the "derive"
or
"full"
feature.
Byte(LitByte)
A byte literal: b'f'
.
This type is available if Syn is built with the "derive"
or
"full"
feature.
Char(LitChar)
A character literal: 'a'
.
This type is available if Syn is built with the "derive"
or
"full"
feature.
Int(LitInt)
An integer literal: 1
or 1u16
.
Holds up to 64 bits of data. Use LitVerbatim
for any larger
integer literal.
This type is available if Syn is built with the "derive"
or
"full"
feature.
Float(LitFloat)
A floating point literal: 1f64
or 1.0e10f64
.
Must be finite. May not be infinte or NaN.
This type is available if Syn is built with the "derive"
or
"full"
feature.
Bool(LitBool)
A boolean literal: true
or false
.
This type is available if Syn is built with the "derive"
or
"full"
feature.
Verbatim(LitVerbatim)
A raw token literal not interpreted by Syn, possibly because it represents an integer larger than 64 bits.
This type is available if Syn is built with the "derive"
or
"full"
feature.
