pub(crate) struct SnippetProvider {
    big_snippet: Lrc<String>,
    start_pos: usize,
    end_pos: usize,
}

Creates a string slice corresponding to the specified span.

Fields

big_snippet: Lrc<String>

A pointer to the content of the file we are formatting.

start_pos: usize

A position of the start of big_snippet, used as an offset.

end_pos: usize

An end position of the file that this snippet lives.

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.
