Struct lib_ruby_parser::nodes::Sym [−][src]
#[repr(C)]pub struct Sym { pub name: StringValue, pub begin_l: Option<Loc>, pub end_l: Option<Loc>, pub expression_l: Loc, }
Expand description
Represents a plain symbol literal (i.e. :foo
)
Note that :
in { foo: bar }
belongs to a pair
node.
Fields
name: StringValue
Value of the symbol literal
Note that it’s a StringValue
, not a String
.
The reason is that you can get UTF-8 incompatible strings
from a valid UTF-8 source using escape sequences like "\xFF"
These “", “x”, “F”, “F” chars are valid separately, but together they construct a char with code = 255 that is invalid for UTF-8.
You can use to_string_lossy
or to_string
methods to get a raw symbol value.
begin_l: Option<Loc>
Location of the symbol begin
:foo
~
None
if symbol is a label ({ foo: 1 }
) or a part of the symbols array (%i[foo bar baz]
)
end_l: Option<Loc>
Location of the symbol end
{ 'foo': 1 }
~
None
if symbol is not a string label (:foo
) or a part of the symbols array (%i[foo bar baz]
)
expression_l: Loc
Location of the full expression
:foo

{ foo: 1 }
