# Struct ManifestErrorContext

Source

    struct ManifestErrorContext {
        path: PathBuf,
        spans: Spanned<DeTable<'static>>,
        contents: String,
        rename_table: HashMap<InternedString, InternedString>,

        cfgs: Vec<Vec<Cfg>>,

Expand description

Cloned and sendable context about the manifest file.

Sometimes we enrich rustc’s errors with some locations in the manifest file; this contains a `Send`-able copy of the manifest information that we need for the enriched errors.

## Fields§

§`path: PathBuf`

The path to the manifest.

§`spans: Spanned<DeTable<'static>>`

The locations of various spans within the manifest.

§`contents: String`

The raw manifest contents.

§`rename_table: HashMap<InternedString, InternedString>`

A lookup for all the unambiguous renamings, mapping from the original package name to the renamed one.

§`requested_kinds: Vec<CompileKind>`

A list of targets we’re compiling for, to determine which of the `[target.<something>.dependencies]` tables might be of interest.

§`cfgs: Vec<Vec<Cfg>>`

A list of all the collections of cfg values, one collection for each target, to determine which of the `[target.'cfg(...)'.dependencies]` tables might be of interest.

§`host_name: InternedString`§`cwd: PathBuf`

Cargo’s working directory (for printing out a more friendly manifest path).

§`term_width: usize`

Terminal width for formatting diagnostics.

## Implementations§

Source§

### impl ManifestErrorContext

Source

#### fn new(build_runner: &BuildRunner<'_, '_>, unit: &Unit) -> ManifestErrorContext

Source

#### fn requested_target_names(&self) -> impl Iterator<Item = &str>

Source

#### fn find_crate_span(&self, unrenamed: &str) -> Option<Range<usize>>

Find a span for the dependency that specifies this unrenamed crate, if it’s unique.

rustc diagnostics (at least for public-in-private) mention the un-renamed crate: if you have `foo = { package = "bar" }`, the rustc diagnostic will say “bar”.

This function does its best to find a span for “bar”, but it could fail if there are multiple candidates:

    foo = { package = "bar" }
    baz = { path = "../bar", package = "bar" }

## 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.
