Struct DebugText 

pub struct DebugText { /* private fields */ }

The debug text of a self-documenting f-string expression (e.g., f"{x=}").

Stores the concatenation of leading text, expression source, and trailing text as a single CompactString, with byte offsets to split them. The offsets are needed because the leading and trailing portions can contain non-whitespace characters (grouping parentheses, comments in triple-quoted f-strings) that cannot be distinguished from expression content by scanning.

Implementations

impl DebugText

pub fn new(leading: &str, expression: &str, trailing: &str) -> Self

pub fn as_str(&self) -> &str

The full debug text between the { and the conversion / format_spec / }.

pub fn leading(&self) -> &str

The text between the { and the expression node.

pub fn expression(&self) -> &str

The source text of the expression (e.g., 0x0 in f"{0x0=}").

pub fn trailing(&self) -> &str

The text between the expression and the conversion, the format_spec, or the }.
