Expand description

Metadata about a target like the description or tier. Part of #120745. All fields are optional for now, but intended to be required in the future.

Fields§

§description: Option<Cow<'static, str>>

A short description of the target including platform requirements, for example “64-bit Linux (kernel 3.2+, glibc 2.17+)”.

§tier: Option<u64>

The tier of the target. 1, 2 or 3.

§host_tools: Option<bool>

Whether the Rust project ships host tools for a target.

§std: Option<bool>

Whether a target has the std library. This is usually true for targets running on an operating system.

impl PartialEq for TargetMetadata

source§

fn eq(&self, other: &TargetMetadata) -> bool
