Trait Implementations

impl Default for StrategySet

Select runtimes from on PATH followed by platform-specific runtimes.

fn default() -> Self

Returns the “default value” for a type.

impl Strategy for StrategySet

fn runtimes(&self) -> Runtimes<'_>

Runtimes known to all strategies, in the same order as each strategy returns them.

Note that runtimes are deduplicated by version number, i.e. if a runtime with the same version number appears in multiple strategies, it will only be returned the first time it is seen.

fn select(&self, version: &PartialVersion) -> Option<Runtime>

Asks each strategy in turn to select a runtime. The first non-None answer is selected.

fn fallback(&self) -> Option<Runtime>

Asks each strategy in turn for a fallback runtime. The first non-None answer is selected.
