#[non_exhaustive]
pub enum BuildTargetKind<'g> {
    LibraryOrExample(&'g [String]),
    ProcMacro,
    Binary,
}
Expand description

The type of build target (library or binary).

Obtained through BuildTarget::kind.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

LibraryOrExample(&'g [String])

This build target is a library or example, with the specified crate types.

The crate types are sorted and unique, and can therefore be treated like a set.

Note that examples are typically binaries, but they may be libraries as well. Binary examples will have the crate type "bin".

For more about crate types, see The crate-type field in the Cargo reference.

§

ProcMacro

This build target is a procedural macro.

This may only be returned for BuildTargetId::Library. This is expressed in a Cargo.toml file as:

[lib]
proc-macro = true

For more about procedural macros, see Procedural Macros in the Rust reference.

§

Binary

This build target is a binary target.

This kind is returned for build script, binary, test, and benchmark targets.
