Struct FileSpan 

pub struct FileSpan {
    pub file: FileId,
    pub span: Span,
}

A Span together with the file it belongs to.

Combining the file into the type means there is no such thing as an “orphan” span whose file has to be guessed from context. Operations that combine two spans (FileSpan::union) require them to share a file, enforced at runtime.

Fields

file: FileId

span: Span

Implementations

impl FileSpan

pub fn new(file: FileId, span: Span) -> FileSpan

pub fn union(self, other: FileSpan) -> Option<FileSpan>

The smallest span covering both self and other.

Returns None if the two spans belong to different files — there is no well-defined union across files, and None forces the caller to handle that case rather than silently picking one.
