Struct TargetMetadata 

pub struct TargetMetadata {
    pub description: Option<Cow<'static, str>>,
    pub tier: Option<u64>,
    pub host_tools: Option<bool>,
    pub std: Option<bool>,
}

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.

Trait Implementations

impl Clone for TargetMetadata

fn clone(&self) -> TargetMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TargetMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TargetMetadata

fn default() -> TargetMetadata

Returns the “default value” for a type.

impl PartialEq for TargetMetadata

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToJson for TargetMetadata

fn to_json(&self) -> Json

impl StructuralPartialEq for TargetMetadata

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.
