Struct rustfmt_nightly::macros::MacroArgParser
source · struct MacroArgParser {
buf: String,
start_tok: Token,
is_meta_var: bool,
last_tok: Token,
result: Vec<ParsedMacroArg>,
}
Expand description
Parses macro arguments on macro def.
Fields§
§buf: String
Either a name of the next metavariable, a separator, or junk.
start_tok: Token
The first token of the current buffer.
is_meta_var: bool
true
if we are parsing a metavariable or a repeat.
last_tok: Token
The last token parsed.
result: Vec<ParsedMacroArg>
Holds the parsed arguments.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
