Struct Config

pub struct Config<'a> {
    pub idents: HashSet<Cow<'a, str>>,
    pub name_values: HashSet<(Cow<'a, str>, Cow<'a, str>)>,
}

A set of enabled named and key-value configuration options.

Fields

idents: HashSet<Cow<'a, str>>

Enabled named configuration options.

name_values: HashSet<(Cow<'a, str>, Cow<'a, str>)>

Enabled key-value configuration options.

Implementations

impl<'a> Config<'a>

pub fn new() -> Self

Creates an empty Config.

pub fn from_package_docs_rs_features(package: &'a Package) -> Self

Creates a Config with features defined in [package.metadata.docs.rs] table in crates’ Cargo.toml.

pub fn with_features<I, T>(self, features: I) -> Self

where I: IntoIterator<Item = T>, T: Into<Cow<'a, str>>,

Extend Config with the feature names from an iterator.

pub fn with_target_arch_os_env(self, target: &str) -> Self

Add target_arch, target_os and target_env Config options from the specified target.

This method require non-default feature platforms.

Trait Implementations

impl<'a> Clone for Config<'a>

fn clone(&self) -> Config<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Config<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Config<'a>

fn default() -> Config<'a>

Returns the “default value” for a type.

impl<'a> PartialEq for Config<'a>

fn eq(&self, other: &Config<'a>) -> 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.
