pub struct Span(_);
🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

A compressed span. Contains either fields of SpanData inline if they are small, or index into span interner. The primary goal of Span is to be as small as possible and fit into other structures (that's why it uses packed as well). Decoding speed is the second priority. See SpanData for the info on span fields in decoded representation.

Return true if the spans are equal with regards to the source text.

Use this instead of == when either span could be generated code, and you only care that they point to the same bytes of source text.
