Struct CoverageSpan

#[repr(C)]
pub(crate) struct CoverageSpan {
    file_id: u32,
    start_line: u32,
    start_col: u32,
    end_line: u32,
    end_col: u32,
}

A span of source code coordinates to be embedded in coverage metadata.

Must match the layout of LLVMRustCoverageSpan.

Fields

file_id: u32

Local index into the function’s local-to-global file ID table. The value at that index is itself an index into the coverage filename table in the CGU’s __llvm_covmap section.

start_line: u32

1-based starting line of the source code span.

start_col: u32

1-based starting column of the source code span.

end_line: u32

1-based ending line of the source code span.

end_col: u32

1-based ending column of the source code span. High bit must be unset.

Implementations

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.
