Struct rustc_span::symbol::Ident[][src]

pub struct Ident {
    pub name: Symbol,
    pub span: Span,
}

Fields

name: Symbolspan: Span

Implementations

Constructs a new identifier from a symbol and a span.

Constructs a new identifier with a dummy span.

Maps a string to an identifier with a dummy span.

Maps a string and a span to an identifier.

Replaces lo and hi with those from span, but keep hygiene context.

“Normalize” ident for use in comparisons using “item hygiene”. Identifiers with same string value become same if they came from the same macro 2.0 macro (e.g., macro item, but not macro_rules item) and stay different if they came from different macro 2.0 macros. Technically, this operation strips all non-opaque marks from ident’s syntactic context.

“Normalize” ident for use in comparisons using “local variable hygiene”. Identifiers with same string value become same if they came from the same non-transparent macro (e.g., macro or macro_rules! items) and stay different if they came from different non-transparent macros. Technically, this operation strips all transparent marks from ident’s syntactic context.

Convert the name to a SymbolStr. This is a slowish operation because it requires locking the symbol interner.

Returns true if the token is a keyword used in the language.

Returns true if the token is a keyword reserved for possible future use.

Returns true if the token is either a special identifier or a keyword.

A keyword or reserved identifier that can be used as a path segment.

We see this identifier in a normal identifier position, like variable name or a type. How was it written originally? Did it use the raw form? Let’s try to guess.

Performs copy-assignment from source. Read more

Formats the value using the given formatter. Read more

This implementation is supposed to be used in error messages, so it’s expected to be identical to printing the original identifier token written in source code (token_to_string), except that AST identifiers don’t keep the rawness flag, so we have to guess it.

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
