Enum rls_vfs::VfsSpan

pub enum VfsSpan {
    UnicodeScalarValue(SpanData),
    Utf16CodeUnit(SpanData),
}

Span of text that VFS can operate with.

Variants

UnicodeScalarValue(SpanData)

Span with offsets based on unicode scalar values.

Utf16CodeUnit(SpanData)

Span with offsets based on UTF-16 code units.
