Struct rustc_expand::mbe::Delimited

struct Delimited {
    delim: DelimToken,
    all_tts: Vec<TokenTree>,
}

Contains the sub-token-trees of a “delimited” token tree such as (a b c). The delimiter itself might be NoDelim.

Fields

delim: DelimToken

all_tts: Vec<TokenTree>

Note: This contains the opening and closing delimiters tokens (e.g. ( and )). Note that these could be NoDelim. These token kinds must match delim, and the methods below debug_assert this.

Implementations

impl Delimited

fn open_tt(&self) -> &TokenTree

Returns a self::TokenTree with a Span corresponding to the opening delimiter. Panics if the delimiter is NoDelim.

fn close_tt(&self) -> &TokenTree

Returns a self::TokenTree with a Span corresponding to the closing delimiter. Panics if the delimeter is NoDelim.

fn inner_tts(&self) -> &[TokenTree]

Returns the tts excluding the outer delimiters.

FIXME: #67062 has details about why this is sub-optimal.

Trait Implementations

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.
