Trait PackageIdSpecQuery

Source 
pub trait PackageIdSpecQuery {
    // Required methods
    fn query_str<I>(spec: &str, i: I) -> CargoResult<PackageId>
       where I: IntoIterator<Item = PackageId>;
    fn matches(&self, package_id: PackageId) -> bool;
    fn query<I>(&self, i: I) -> CargoResult<PackageId>
       where I: IntoIterator<Item = PackageId>;
}

Required Methods§

Source

fn query_str<I>(spec: &str, i: I) -> CargoResult<PackageId>
where I: IntoIterator<Item = PackageId>,

Roughly equivalent to PackageIdSpec::parse(spec)?.query(i)

Source

fn matches(&self, package_id: PackageId) -> bool

Checks whether the given PackageId matches the PackageIdSpec.

Source

fn query<I>(&self, i: I) -> CargoResult<PackageId>
where I: IntoIterator<Item = PackageId>,

Checks a list of PackageIds to find 1 that matches this PackageIdSpec. If 0, 2, or more are found, then this returns an error.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
